Clarity Chromatography Software 10.2 released!

<p><strong>Traditional EI library searching works exceptionally well when the unknown compound is already present in the spectral library. However, analytical chemists frequently encounter compounds that are structurally related to library entries but are not exact matches. NIST's EI Hybrid Search addresses this challenge by combining conventional spectral matching with mass-shifted fragment alignment, allowing the identification of analogs, derivatives, and novel compounds that may not exist in the database.</strong></p><p>This guide summarizes the workflow presented by James Little and demonstrates how to use NIST 26 Hybrid Search in conjunction with the Chromatogram Window and MS Interpreter to obtain more meaningful structural information from unknown EI GC-MS spectra.</p><blockquote><p><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/paper/33370"><strong>You can download PDF Handout for this guide HERE</strong></a></p></blockquote><h4><strong>Why Hybrid Search Matters</strong></h4><p>Conventional EI library searching relies on direct matching between an unknown spectrum and spectra stored in a library. Hybrid Search expands this concept by allowing fragment ions to be matched even when they are shifted by a consistent mass difference (Δm). This enables the software to recognize compounds that differ by substituents or structural modifications.</p><p><strong>Key advantages include:</strong></p><ul><li>Identification of structurally related compounds not present in the library</li><li>Detection of analogs, derivatives, and emerging compounds</li><li>Integration of exact fragment matches and mass-shifted matches into a single score</li><li>Improved interpretation of unknowns through proposed structural modifications</li><li>Enhanced confidence when molecular weight information is available</li></ul><p>Although Hybrid Search does not require the molecular ion to be present, performance improves significantly when the molecular weight can be estimated or constrained. In these cases, the observed mass difference between the unknown and library compounds can often be translated directly into a plausible chemical modification.</p><h4><strong>Configuring Hybrid Search</strong></h4><p>Before performing a search, the Hybrid Search settings should be configured within the NIST Library Search window.</p><p>Recommended settings:</p><ul><li>Select the Similarity search mode</li><li>Enable Hybrid Search</li><li>Keep the In Spectrum option checked under normal circumstances</li><li>Allow the software to estimate the molecular weight automatically</li><li>If the estimated molecular weight appears incorrect, manually enter a nominal molecular weight</li><li>Select all relevant libraries (NIST, Wiley, user libraries, etc.)</li><li>Save the configuration for future use</li></ul><p>The selected molecular weight used to constrain the search is displayed in the lower-right corner after the search is completed.</p><h4><strong>Optimizing the Results Display</strong></h4><p>Hybrid Search produces several unique parameters that are not shown in the default results table.</p><p>Additional columns should be added by right-clicking within the results table and selecting Properties. Recommended columns include:</p><ul><li>DeltaMass</li><li>dForm</li><li>pctRelForm</li><li>o.Match (equivalent to the traditional EI Normal Match score)</li></ul><p>Without these parameters, much of the structural interpretation power of Hybrid Search is lost.</p><h4><strong>Working with Spectra from the Chromatogram Window</strong></h4><p>Currently, the Chromatogram Window performs standard EI library searching. When a potentially interesting unknown is encountered:</p><ul><li>Perform the normal EI search in the Chromatogram Window</li><li>Send the spectrum to the standalone Library Search module</li><li>Perform a Hybrid Search using the enhanced Hybrid Search functionality</li></ul><p>This workflow combines rapid screening with advanced structural interpretation.</p><h4><strong>Understanding Key Hybrid Search Parameters</strong></h4><h5><strong>DeltaMass (Δm)</strong></h5><p>DeltaMass represents the mass difference between the unknown compound and the matched library compound.</p><p>A consistent Δm across multiple high-scoring hits often indicates a specific structural modification.</p><h5><strong>dForm</strong></h5><p>dForm provides a proposed elemental composition that explains the observed mass difference.</p><p>Examples include:</p><ul><li>H–1F</li><li>CH₂</li><li>O–1</li><li>C₁H₃F</li></ul><p>These transformations can suggest likely chemical modifications between the library compound and the unknown.</p><h5><strong>pctRelForm</strong></h5><p>New in NIST 26, pctRelForm estimates how frequently a given elemental transformation occurs relative to the most common transformation (CH₂ = 100%).</p><p>Interpretation:</p><ul><li>High values indicate chemically plausible and commonly observed transformations</li><li>Very low values suggest the proposed transformation may be accidental or unlikely</li></ul><h5><strong>o.Match</strong></h5><p>Represents the traditional EI match score and allows comparison between standard searching and Hybrid Search results.</p><h4><strong>Case Study: Identifying a Fluorinated Unknown</strong></h4><p>The presentation demonstrates the identification of an unknown compound with a proposed molecular weight of 152 Da.</p><p>Hybrid Search returned several high-scoring hits with consistent evidence suggesting fluorine substitution:</p><p><strong>Hit #1</strong></p><ul><li>Library MW: 134</li><li>DeltaMass: +18</li><li>dForm: H–1F</li><li>Interpretation: Addition of fluorine</li></ul><p><strong>Hit #5</strong></p><ul><li>Library MW: 138</li><li>DeltaMass: +14</li><li>dForm: CH₂</li><li>Interpretation: Related fluorinated analog</li></ul><p><strong>Hit #6</strong></p><ul><li>Library MW: 168</li><li>DeltaMass: –16</li><li>dForm: O–1</li><li>Interpretation: Structurally consistent fluorinated compound</li></ul><p>Multiple independent hits converged on the same conclusion: the unknown was likely a fluorinated analog of known aromatic compounds.</p><p>This illustrates the major strength of Hybrid Search: identifying structural relationships even when the exact compound is absent from the library.</p><h4><strong>Moving from Hybrid Search to Structural Interpretation</strong></h4><p>Once a plausible structure is identified:</p><h5><strong>Step 1 – Export the Structure</strong></h5><p>From the Hybrid Search results:</p><ul><li>Right-click the best hit</li><li>Use Send To → Default Structure Editor</li><li>Open the structure in a drawing program such as ChemSketch</li><li>Copy the proposed structure to the clipboard</li></ul><h5><strong>Step 2 – Open MS Interpreter</strong></h5><p>Within MS Interpreter:</p><ul><li>Paste the proposed structure</li><li>Load the unknown spectrum</li><li>Compare predicted fragmentation with observed ions</li><li>Evaluate isotope patterns and fragment assignments</li></ul><h5><strong>Step 3 – Validate the Proposal</strong></h5><p>Indicators of a good structural proposal include:</p><ul><li>Consistent isotope ratios</li><li>Logical fragmentation pathways</li><li>Agreement between observed and predicted fragment ions</li><li>Multiple Hybrid Search hits supporting the same structural modification</li></ul><p>In the example presented, MS Interpreter showed excellent agreement between the proposed fluorinated structure and the observed EI spectrum, although the exact positions of the fluorine and methyl substituents on the aromatic ring could not be definitively assigned.</p><h4><strong>Best Practices</strong></h4><ul><li>Always review DeltaMass, dForm, and pctRelForm together</li><li>Do not rely solely on the highest match score</li><li>Give greater weight to transformations supported by multiple independent hits</li><li>Use molecular weight information whenever possible</li><li>Confirm structural hypotheses using MS Interpreter</li><li>Consider Hybrid Search as a structure-elucidation tool rather than simply a library search tool</li></ul><h4><strong>Conclusion</strong></h4><p>NIST 26 Hybrid Search significantly extends the capabilities of conventional EI library searching by identifying structural relationships between unknown compounds and library entries. Through the use of DeltaMass calculations, elemental transformation analysis (dForm), and statistical plausibility metrics (pctRelForm), Hybrid Search provides valuable clues for elucidating compounds that are absent from spectral libraries.</p><p>When combined with MS Interpreter, it becomes a powerful workflow for the characterization of unknowns, analogs, degradation products, metabolites, and emerging compounds in EI GC-MS analysis.</p>

VOCs from decomposing remains have been studied before,1 however there is a gap that remains in the knowledge on VOCs that evolve from submerged decomposing remains. 2 In this study, submerged animal tissue was tested to see how the VOCs can be utilized in forensic settings.&nbsp;</p><p>This study used data obtained last summer using comprehensive two-dimensional gas chromatography – time-of-flight mass spectrometry (GC×GC-TOFMS). Pigs (Sus scrofa domesticus) are often used as analogs in decomposition studies due to similarities with humans. 3 In this study, pork belly samples were submerged in mason jars filled with water and stored at different temperatures. The GC×GC-TOFMS instrument was used to collect odor from above water samples for a period of twelve days.</p><p>GC×GC is often used to analyze complex odor profiles. When analyzing samples with GC×GC, there is a lack of standardization to process the data acquired from time trials. There is a need to discover effective ways to track VOCs for chemical identification and longitudinal analysis.</p><p>The goal of this research was to compare different software approaches to analyze GC×GC longitudinal data to achieve accurate analyte identification, representation of data over time, and effective class characterization.</p><h4><strong>Methods</strong></h4><p>For the first four days, 5 mL of water was taken and run on the <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/37"><strong>GC×GC-TOFMS</strong></a>. Thereafter, the samples were sampled and run every three days until day twelve. Data were analyzed initially using <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/41"><strong>ChromaTOF</strong></a> (LECO Corporation). The samples were then analyzed using <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/348"><strong>ChromaTOF Tile </strong></a>and <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/1873"><strong>ChromaTOF Sync 2D</strong></a> to compare how they can be used in a forensic setting.</p><p>Peak tables were curated in Tile and Sync 2D. Then, ChromaTOF was used as a guide to confirm which peaks were identified correctly. If the compound was correctly identified, the peak would be accepted or kept on the table. If not correctly identified, the peak would either be rejected or deleted. Once the tables were complete from the different software approaches, they were exported to Excel for further comparison.</p><p>In excel, the relevant hits that were identified as decomposition VOCs were compared across the software approaches. The compounds that were most commonly found were compared to existing literature on decomposition VOCs. From there, two tables were built; where one table was compounds confirmed with literature and the other table was compounds not confirmed with literature.</p><p>Comparison between software approaches included looking at different criteria to see which method was the most effective and efficient. The criteria included how long the software approach took, the number of compounds found in each software approach, the accuracy of peak area in the software approach compared to ChromaTOF data, and principal component analysis (PCA) comparison to see which software approach was best used for forensic practice or research.</p><h4><strong>Conclusions</strong></h4><p>Sync 2D showed the capability of showing trends in decomposition compounds</p><ul><li>This software approach can be used in research environment where longitudinal data is needed to determine the trends of decomposition data&nbsp;</li><li>Best purpose: research applications requiring longitudinal tracking&nbsp;</li></ul><p>Coefficient of Variance’s and Fold Change’s PCA plots showed their ability for clear class differentiation&nbsp;</p><ul><li>The two software approaches can be used to distinguish water containing decomposition in a crime scene&nbsp;</li><li>Best purpose: comparison at a single point and time [detailed analysis]&nbsp;</li></ul><p>Fisher Ratio showed a proficiency in identifying top differentiating compounds and showed aptitude for class differentiation&nbsp;</p><ul><li>The software approach would be helpful for cursory analysis for crime scene evidence&nbsp;</li><li>Best purpose: quick comparison of biggest difference for swift identification</li></ul><h3><strong>3.

They can be produced from a range of raw materials, including plant oils, animal fats, and used cooking oils. Biodiesel is mainly being produced from rapeseed, soybean, and palm oils. Due to this diversity of feedstocks, continuous quality control is necessary as the quality of the raw material has an enormousimpact on the quality of the biodiesel.&nbsp;</p><p>The EN 14103:2020 describes the determination of total ester content and linolenic acid methyl ester content in biodiesel by means of gas chromatography with flame ionization detection (GC-FID). The total ester content covers a range of fatty acid methyl esters (FAME) from C6 to C24, and linolenic acid methyl ester is investigated separately as interfering reactive compound that might influence long-term stability of the biodiesel. According to the standard, the total ester content must be greater than 90 % (m/m) and the linolenic acid methyl ester content shall be between 1 and 15 % (m/m)1.</p><p>This study shows the analysis of biodiesel originating from rapeseed,soybean, and palm oil using the Nexis GC-2060.</p><h4><strong>Multi-Mode Injection Unit as Alternative&nbsp;</strong></h4><p>Shimadzu’s multi-mode injection unit (MMI) offers reliable splitsplitless mode functionality over a broad range of carbon numbers. It allows analysis of biodiesel samples with high repeatability and provides chromatographic results comparable to those measured with SPL as dedicated split-splitless injection unit. The use of MMI significantly shortens maintenance downtime from tens of minutes for a classical split-splitless injection unit to just a few minutes. Figure 3 gives a direct comparison of an exemplary rapeseed-based biodiesel sample measured with SPL (top) and MMI (bottom).</p><h4><strong>Conclusion</strong></h4><p><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=1&amp;search=2060"><strong>Nexis GC-2060</strong></a> provides reliable analysis of biodiesel samples regarding their ester and linolenic acid methyl ester content according to EN 14103:2020, covering the various ester types commonly in use. It allows repeatable analysis using hydrogen as a cost-effective carrier gas. The optional multi-mode injection unit (MMI) can be selected as alternative to a classical splitsplitlessinjection unit (SPL).</p><h3><strong>4. Waters Corporation / ASMS: Putting the (Atmospheric) Pressure on Forever Chemicals: A Targeted Analysis of GC Amenable PFAS using APGC–MS/MS</strong></h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/720009413_dfa4082b45.pdf"><strong>Full PDF for download</strong></a></li></ul><p>This poster presents a targeted analytical method for the determination of gas chromatography (GC)-amenable PFAS compounds using atmospheric pressure gas chromatography coupled with tandem mass spectrometry (APGC-MS/MS). The study addresses a key limitation of conventional LC-MS/MS methods, which are highly effective for many PFAS but less suitable for more volatile species such as fluorotelomer alcohols (FTOHs), fluorotelomer acrylates (FTAcr), and fluorotelomer acetates (FTOAc). By incorporating GC-MS/MS analysis, laboratories can obtain a more complete characterization of PFAS contamination across environmental, biological, and food-contact materials.</p><p>The analytical workflow utilized an <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/library?mainauthorItems=10&amp;search=8890"><strong>Agilent 8890 gas chromatograph</strong></a> equipped with an autosampler and coupled to a <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/554"><strong>Waters Xevo TQ Absolute tandem mass spectrometer</strong></a> operated with APGC ionization in positive-ion mode. Separation was performed on an Rtx-200 capillary column, while data acquisition and quantification were managed using <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1544"><strong>waters_connect software</strong></a>. Unlike traditional electron ionization (EI), APGC generated intact protonated molecular ions, significantly improving sensitivity and selectivity for GC-amenable PFAS. A method covering 35 PFAS compounds was developed, achieving lower limits of quantification (LLOQs) of 0.025–0.1 ng/mL for most analytes.</p><p>Several sample types were evaluated, including wastewater, surface water, soil, fish tissue, shrimp, and food-packaging materials. Environmental and biological samples were prepared according to EPA Method 1633A and had previously been analyzed by LC-MS/MS, allowing the GC-MS/MS method to serve as a complementary technique. Food-packaging samples were extracted with methanol containing ammonium hydroxide and analyzed for targeted PFAS. While no target PFAS were detected in the tested packaging materials, multiple GC-amenable PFAS were found in environmental samples. Fluorotelomer alcohols were the most frequently detected compounds, with wastewater and ski-wax-impacted soils showing the highest concentrations.</p><p>The results demonstrate that APGC-MS/MS provides a sensitive and robust solution for the analysis of volatile PFAS classes that may be missed by LC-MS/MS alone. The method delivered accurate quantification, effective chromatographic separation, and reliable recovery in spiked samples. The authors conclude that combining APGC-MS/MS with established LC-MS/MS workflows enables a more comprehensive assessment of PFAS contamination, particularly for emerging fluorotelomer compounds and other GC-amenable PFAS that are increasingly relevant in environmental monitoring and food-packaging investigations.</p></div></div></div></div></div></div></section></div></div></div></div></div></div></section>

Some scientists have even experienced total analyte loss with samples stored in vials for an extended time. The vial chemistry, specifically the&nbsp;glass surface, is the major contributor to this problem.</p><p>Polar analytes&nbsp;may adsorb to the glass vial surface by polar-polar interaction and/or ion exchange mechanisms, thereby reducing the overall amount of sample in solution. TruView Certified LCMS Vials&nbsp;reduce this problem dramatically due to a stringent manufacturing process. The process yields a glass surface that has a lower concentration of free ions on the surface.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_CERTIFIED_Vials_8_064003b933.jpg" alt="Waters CERTIFIED Vials: Nortriptyline at 1 ppb concentration in several vials.

height="386"></p><h4><strong>Sample preparation, improved</strong></h4><p>Improving various aspects of chromatography and mass spectrometry analyses often starts with sample preparation. &nbsp;Solid-phase extraction (SPE) or "liquid-solid phase extraction" is a sample preparation technology that uses particles of chromatographic packing material, usually in a cartridge or 96-well plate format, to chemically separate different analytes and aid in removing matrix components in a sample. &nbsp;</p><p>SPE is a proven sample preparation tool for simple sample matrix removal, including common interferences like proteins, salts, fats and phospholipids. This matrix removal provides many benefits, including matrix effect reduction and an increase in sample concentration and analyte specificity.

LECO QuadJet™ SD

GC×GC-FID system combining thermal modulation and ChromaTOF software to reduce coelution bias, boost resolution, and deliver accurate quantitation of complex samples—without sacrificing productivity.

<p><strong>The QuadJet SD is a comprehensive GC×GC-FID solution designed to reveal the true chemical composition of complex real-world samples. By combining the universal sensitivity of flame ionization detection (FID) with the dramatically increased chromatographic resolution of comprehensive two-dimensional gas chromatography (GC×GC), QuadJet SD minimizes coelution-driven bias and delivers a far more accurate representation of sample composition than conventional one-dimensional GC.</strong></p><p>Unlike straight GC-FID, where unresolved peaks inflate detector response and introduce systematic error, GC×GC separates compounds using two orthogonal mechanisms within a single run. True GC×GC instruments—such as the QuadJet SD from <span>LECO</span>—use active modulation to quantitatively slice the effluent from the first column and refocus it onto the second column. This approach preserves quantitative integrity while unlocking orders-of-magnitude gains in peak capacity and signal-to-noise ratio.</p><h3><strong>Key Benefits</strong></h3><ul><li><strong>Enhanced separation power</strong> for highly complex mixtures</li><li><strong>Reduced noise and bias error</strong> compared to conventional GC-FID</li><li><strong>Integrated </strong><a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/products/41"><strong>ChromaTOF-based software</strong></a> for acquisition, processing, classification, and reporting in one environment</li><li><strong>Classification tools</strong> that simplify component identification</li><li><strong>Cryogen-free modulation option</strong> eliminates the need for liquid nitrogen dewars</li></ul><h3><strong>Theory of Operation</strong></h3><p>In GC-FID analysis, compound quantitation relies on peak area. As sample complexity increases—diesel fuels being a classic example with thousands of constituents—the likelihood of coelution rises sharply. Coeluting compounds produce artificially elevated FID responses, leading to high-bias errors.</p><p>GC×GC overcomes this limitation by performing two independent chromatographic separations in a single experiment. Thanks to the orthogonal selectivity of the two columns, compounds that coelute in the first dimension are efficiently separated in the second. In the QuadJet SD, eluting peaks from the primary column are quantitatively segmented by the modulator and cryo-focused before entering the secondary column, generating extremely narrow second-dimension peaks—often as short as <strong>50 ms</strong>—while maintaining accurate quantitation.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/LECO_Quad_Jet_SD_2_bbb51b2254/LECO-QuadJettm-SD-2_l.webp" alt="LECO: QuadJet™ SD 2 – Processing of acquired GC×GC data using LECO ChromaTOF software" width="923" height="543"></p><h3><strong>Thermal Modulation</strong></h3><p>Thermal modulation represents the highest-performance approach for GC×GC, and LECO’s implementation sets the benchmark for ruggedness, reliability, and analytical performance. The QuadJet SD employs a <strong>dual-stage, quad-jet thermal modulator</strong> positioned between the two columns. This design enables on-column cryo-focusing, dramatically improving peak detectability and resolving power, and delivering an <strong>order-of-magnitude improvement in signal-to-noise</strong>.</p><p>For laboratories seeking lower operating costs and simplified workflows, a <strong>consumable-free thermal modulator</strong> (no liquid nitrogen) is available. This option maintains excellent performance for moderately volatile compounds while eliminating cryogen handling.</p><h3><strong>Modulators and Instrument Options</strong></h3><ul><li><strong>Thermal modulator choices</strong>:<ul><li>Liquid-nitrogen-cooled thermal modulator</li><li>Consumable-free thermal modulator</li></ul></li><li><strong>Optional inlets</strong>: S/SL, PTV, and MMI</li></ul><p>Designed with productivity in mind, the QuadJet SD combines ease of use with an industry-leading secondary oven for the second-dimension column. For laboratories ready to move beyond conventional GC and truly see what has been hidden by coelution, QuadJet SD delivers the next dimension in analytical insight.</p>

LECO ChromaTOF® Tile analytical software

ChromaTOF Tile enables rapid, statistically robust GC×GC-TOFMS data comparison using tiled heatmaps, reducing false positives and cutting data mining from days to minutes.

<p><strong>Turn Your Data into Chemistry</strong></p><p><strong>The volume of GC×GC-TOFMS data can quickly become overwhelming. Thousands of analytes across multiple tables may require months of pixel-level data mining, often complicated by false positives caused by normal chromatographic variation.</strong></p><p><strong>ChromaTOF Tile</strong> fundamentally changes how GC×GC data are compared and interpreted. Instead of evaluating individual pixels, the software statistically compares tiled regions of chromatograms. Truly significant differences rise immediately to the surface—allowing you to focus on chemical meaning rather than data hunting.</p><blockquote><p><i>“ChromaTOF Tile is an enabling technology that has reduced our peak picking time from 10 days to 10 minutes.”</i></p></blockquote><h3><strong>Designed for Sample Group Differentiation</strong></h3><p>Integrated heatmap tables provide instant visual feedback on relative intensities and variance.
