Shimadzu: <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/TP_093_Analysis_of_PFAS_in_Water_Final_05292024_8fa9fcb27d.pdf">Analysis of Volatile PFAS in Water Using Head-Space Solid Phase Microextraction- Gas Chromatography/Mass Spectrometry (HS-SPME GC/MS)</a></h4><ul><li>Poster / <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/companies/296">ASMS</a>&nbsp;</li></ul>Introduction&nbsp;Per- and Polyfluoroalkyl Substances (PFAS) are environmental pollutants with recognized health and environmental concerns due to their probable toxicity, persistence, and ubiquitousness throughout the environment, and consumer and industrial products. PFAS encompass a large family of chemicals with varying physicochemical properties. These properties not only affect their toxicity and environmental fate, but also complicates chemical analysis.In this work, a Head-Space Solid Phase Microextraction-Gas Chromatography/Mass Spectrometry (HS-SPME GCMS) analytical method was developed to analyze six classes of volatile PFAS in water. This HS-SPME method presents the advantage of simplifying sample extraction and handling for the analysis of volatile PFAS in water, hence, minimizing operational costs, potential errors, and risk of sample-cross contamination.ConclusionThis study demonstrated the use of a Shimadzu GC/MS-QP2020 NX single quadrupole instrument configured with the AOC-6000 Plus multifunctional autosampler and an automated head space solid phase microextraction unit for measurement of volatile PFAS compounds in water. Linear calibration curves were obtained for all compounds (R 2 ≥ 0.993 and RF %RSD &lt; 20 %). The HS-SPME GC/MS-QP2020 NX method demonstrated qualitative and quantitative capability of analyzing PFAS compounds.<h4>2. Thermo Fisher Scientific: <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_003028_gc_ms_isq_epa_vocs_an003028_na_en_7646797ef5.pdf">Analysis of volatile organic compounds in drinking water according to U.S. EPA Method 524.4</a></h4><ul><li>Application</li></ul>GoalDemonstration of an analytical method that meets the requirements outlined in U.S. EPA Method 524.4 for the quantitation of volatile organic compounds (VOCs) in drinking water, using the Teledyne LABS Tekmar Lumin Purge and Trap (P&amp;T) concentrator paired with the AQUATek LVA autosampler system along with a Thermo Scientific™ ISQ™ 7610 MS system coupled with a Thermo Scientific™ TRACE™ 1610 gas chromatograph (GC) and Thermo Scientific™ Chromeleon™ Chromatography Data System (CDS). Target analyte linearity, method detection limit (MDL), minimum report level (MRL), and mid-point precision and accuracy were assessed to evaluate method performance.Keywords: EPA, U.S. EPA 524.4, VOCs, phthalates, trace analysis, gas chromatography, single quadrupole mass spectrometry, selected ion monitoring, sensitivity, GRO, THM, volatiles, environmental lab, environmental sample analysis, analytical testing laboratories, ISQ 7610 MS, TRACE 1610 GC, GC-MS.IntroductionVolatile organic compounds (VOCs) are man-made contaminants in various products that pose environmental and public health risks. These compounds are regulated in drinking water, and laboratories follow regulations including U.S. EPA Method 524.2.1 A previous application note described U.S. EPA Method 524.2,2,3 which is the most common method for VOC water testing in the USA. U.S. EPA Method 524.4 is an updated method that allows for nitrogen to be used as the purge gas, thus reducing helium consumption, and is now being more widely used. Targeting 75 VOCs, this method differs by offering more method parameter flexibility but stricter quality control, including the stringent calculation of the minimum reporting level for evaluating calibration checks.Implementing U.S. EPA Method 524.4 can present multiple challenges for laboratories. Striking a balance between optimized method conditions and meeting the acceptance criteria, like detection limit requirements for various compound concentrations, is pivotal. Another major hurdle is managing the water matrix to minimize GC-MS system water introduction, which could lead to detrimental effects and delay sample reporting, thereby increasing public safety risks. Ultimately, maintaining consistency in test results to avoid sample reanalysis is crucial. Another factor for laboratories to consider is the fluctuating cost of helium, which is the analytical gas of choice for this analysis. Reducing the use of helium—a limited resource—will enable the laboratory to reduce operational costs and increase profitability.The following evaluation describes the use of the ISQ 7610 GC-MS system coupled with a TRACE 1610 GC with the Thermo Scientific™ HeSaver-H2Safer™ split/splitless injector and Teledyne LABS Tekmar Lumin P&amp;T concentrator paired with the AQUATek LVA autosampler for U.S. EPA Method 524.4.ConclusionThe combined solution of the TRACE 1610 GC coupled with the ISQ 7610 system and the Tekmar Lumin P&amp;T concentrator with the AQUATek LVA autosampler system successfully addresses the challenges of VOC analysis and provides a robust, sensitive solution needed for ensuring maximized sample throughput and regulatory method compliance for U.S. EPA Method 524.4.<ul><li>Excellent linearity for all compounds was demonstrated with the linear regression (r²≥0.995) of the calibration response factors passing all method requirements.</li><li>MDL and precision for seven 0.5 ppb standards showed no interference from excessive water and produced very reproducible results.</li><li>The precision for n=30 samples over 245 injections displayed &lt;30% RSD for all compounds as the method requires and an average recovery of 91%.</li><li>Utilizing HeSaver-H2Safer technology reduced helium consumption for the method by 4 times, which provides a significant cost savings.</li></ul><h4>3. Waters Corporation: <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/720008298_en_db4158391c.pdf">Extractables Analysis of Nasal Spray Devices Using Gas Chromatography and High- Resolution Mass Spectrometry With Soft Ionization</a></h4><ul><li>Application</li></ul>AbstractDue to concern about the safety of components from plastic, it is crucial to screen for and identify potential extractables and leachables (E&amp;L) in pharmaceutical packaging and medical devices. For volatile, and semi-volatile compounds, gas chromatography-mass spectrometry (GC-MS) with electron ionization (EI) is typically used. Compounds are determined using scientific libraries; however, where compounds are not listed or where the sensitivity of EI-MS is not sufficient, the identification process becomes challenging.Here, we describe an E&amp;L screening experiment using gas chromatography and a quadrupole time of flight high-resolution mass spectrometer (QToF-HRMS) with atmospheric pressure gas chromatography (APGC) for soft ionization. A data independent acquisition (DIA) strategy is utilized to aid screening and elucidation which are combined in a screening software solution.Benefits<ul><li>GC-QToF MS with APGC as an orthogonal technique to LC-QToF-MS allows for comprehensive compound coverage with increased sensitivity compared to typical EI techniques</li><li>The UNIFI™ application within the waters_connect™ platform provides customized workflows to simplify screening and structural elucidation in complex datasets</li><li>The Xevo™ G3 QTof Mass Spectrometer enables confident identification of E&amp;L components in complex matrices through novel ion optics and detection system which maximize transmission</li><li>Soft ionization using the APGC™ source allows for the detection of molecular ions from which elemental compositions can be derived to aid compound identification and confirmation&nbsp;</li><li>MSE, a data independent acquisition, increases confidence in identifications when screening against a library and provides additional information to aid structural elucidation</li></ul>Conclusion&nbsp;When undertaking E&amp;L screening analyses it is important to use a range of analytical techniques to account for different compound chemistries. GC-QToF MS with APGC as an orthogonal technique to LC-QToF-MS allowed for comprehensive compound coverage with increased sensitivity compared to typical EI techniques. Due to the soft ionization of APGC, the intact molecular ion is often present in the spectra. This combined with a data independent acquisition, MSE mode, utilizes full spectral acquisition of the accurate mass information of both precursor and fragment ions.This approach boosts confidence in component identifications when screening against an MS/MS library, while minimizing false positives. For instance, in the LC-QToF-MS there were just under 40 potential compounds matches in sample E48 after considering factors such as retention time match, mass accuracy below 3 ppm, and the presence of at least one fragment ion. A further 38 compound matches in sample E48 were tentatively identified using GC-QToF MS with APGC, with mass accuracy below 3 ppm, and the presence of at least one fragment ion.MSE data also aids in the structural elucidation of unknown substances by utilizing accurate mass and corresponding fragment ions, facilitating comprehensive characterization. This data increases confidence in identifications of components and assists with structural elucidation of unknowns to ultimately aid full characterization. For example an unknown with protonated m/z 284.2703 was tentatively identified as a N-(2-(1-piperazinyl)ethyl)decanamide (mass error 2.33 ppm) by the software.For the extractables analysis of nasal sprays the UNIFI application within the waters_connect platform provided SST benchmarking, screening against a library, summary plots to identify trends, filtering of AET levels, binary compare mode to isolate relevant unknowns, and a Discovery Tool for elucidation of unknowns.<h4>4. Agilent Technologies: <a target="_blank" rel="noopener noreferrer" href="https://gcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_voc_rubber_gasket_extracts_gc_msd_5994_7777en_agilent_6a0a6bf7d0.pdf">Analysis of Volatile Compounds Identified in Rubber Gasket Extracts Using GC/MSD and High-Resolution GC/Q-TOF</a></h4><ul><li>Application</li></ul>AbstractChemicals that are part of polymeric container closure systems (CCS) and drug delivery systems have the potential to migrate into drug products during manufacturing, storage, transport, and delivery, and must be identified in the final products to ensure their safety.This application note presents a rubber gasket extractables study using a unit mass resolution gas chromatography/mass selective detector (GC/MSD) and a high-resolution gas chromatography/quadrupole time-of-flight (GC/Q-TOF) mass spectrometer to establish a process for identifying GC-amenable extractables and leachable (E&amp;L) compounds.IntroductionElastomeric gaskets, plungers, and O-rings are common sources of leachable compounds in the manufacturing, storage, and delivery of drug products. E&amp;Ls derived from elastomeric components may impact the stability and efficacy of small and large molecule drug products1, and therefore need to be characterized thoroughly. Exposure to some E&amp;L chemicals, such as phthalates and nitrosamines, even at low levels, may cause safety concerns.2 Chemicals derived from the elastomer manufacturing process typically include accelerators, activators, antioxidants, fillers, plasticizers (including phthalates), mold release agents, and other additives3 that may leach into the final product. Some additives present in elastomer packaging materials may also contain polycyclic aromatic hydrocarbons (PAHs)4 and aliphatic hydrocarbons.GC/MS is a commonly used technique for analyzing volatile and semivolatile organic compounds in the E&amp;L space. This study demonstrates the capabilities of GC/MSD to identify GC-amenable compounds present in a solvent extract of a rubber gasket by leveraging chromatographic deconvolution in combination with retention index (RI)-based filtering. Adding a high-resolution accurate mass GC/Q-TOF into the E&amp;L workflow provided a higher number of identified chemicals. It also increased confidence in compound identification and enabled structure elucidation of unknown compounds.The study was performed in the Network Workstation configuration using Agilent OpenLab Electronic Content Management (ECM) XT as the data repository. This configuration enabled tools that facilitate compliance with various national and EU electronic record regulations, including audit trails, user authentication, role-based permission controls, and remote data storage.5ConclusionThe GC/MSD is an effective and accessible tool for the analysis of volatile and semivolatile compounds in complex E&amp;L extracts. The established workflow includes deconvolution and an RI-based library search with the data acquisition performed in a compliant environment.The high-resolution Agilent 7250 GC/Q-TOF enabled the identification of additional components with increased confidence, as well as structure elucidation of the unknown compounds.Furthermore, using the novel ultra-low bleed Agilent J&amp;W DB-5Q GC column resulted in a significant decrease in background, which helps in the identification of late-eluting compounds.

Watrex LSS-205 Liquid Sensing System

Liquid Sensing System LSS-205 is a universal sensing system for monitoring the level of your chromatographic system liquids.

Universal sensing system for monitoring the level of your chromatographic system liquids. The daily task in the chromatographic laboratory is the manipulation of mobil phases. The operator must check the supply of solvents at the inlet of the device and regular monitor the condition of the waste solvent container. The LSS-205 greatly simplifies these tasks.<blockquote>Price: 578<bdi>&nbsp;€ ex VAT</bdi></blockquote>LSS-205 is a universal accessory for any (chromatographic) system. The level sensors used in the LSS-205 system are contactless, do not require immersion in liquid, and are installed on the outer shell of a non-metallic solvent container.

ARC Polyarc System

A Breakthrough Innovation Revolutionizing GC/FID Technology. The Polyarc System is transforming the way scientists use gas chromatographs with Flame Ionization Detectors.

The Polyarc system has a catalytic microreactor that enhances new and existing gas chromatographs (GCs) with flame ionization detectors (FIDs) by converting all organic compounds to methane molecules prior to their detection by the FID. In doing so, the Polyarc system reduces the need to perform time-consuming calibrations by creating a uniform detector response for truly universal carbon detection.
The Polyarc system gives scientists the capability to determine purity, quantify unknowns, qualify products, investigate, improve development and more in a simple, fast and more economical way that is transforming the industry.

<h3>What is Polyarc?</h3>
The Polyarc is the next evolution of flame ionization detection (FID). The Polyarc converts the FID into a truly universal carbon detector using proprietary catalytic reactions that convert organic molecules to methane immediately prior to detection.
<h3>Why is it important?</h3>
The FID has two main challenges: lack of uniform response and low response to certain compounds. The Polyarc enhances your FID to solve these challenges by giving your FID a uniform response to nearly all organic molecules. The result is more accurate data, improved productivity, lab efficiencies, and the ability to detect more compounds.
<h3>How Does the Polyarc® System Work to Simplify and Improve GC/FID Quantification?</h3>
The Polyarc system has a catalytic microreactor that enhances GC/FIDs by converting all organic compounds to methane molecules prior to detection by the FID. The result?
A universal response for ALL organic molecules.

<h3>The Polyarc System Features an Optimized Design and Seamless Integration</h3>
The Polyarc system is the first commercial technology of its kind. The device uses proprietary technologies including novel catalysts, a specially designed 3D-printed micro reactor, and fast seamless integration into existing equipment.
The optimized internal design and catalyst microstructure maintains separation performance and peak shape while increasing sensitivity and enabling accurate quantification without calibration standards.

ARC Jetanizer (Methanizer)

The Jetanizer is the easiest and most robust methanizer.

<h3>What is Jetanizer™?</h3>
The Jetanizer is the easiest and most robust methanizer. A methanizer is a chemical reactor that converts carbon dioxide and carbon monoxide to methane to enable sensitive detection by a flame ionization detector (FID) from &lt;20 ppb to 100%!
<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ARC_Analyza_CO_2_od_1ppm_do_100_s_pouzitim_GC_jetanizeru_FID_9c922be2e9/ARC-Analyza-CO2-od-1ppm-do-100percent-s-pouzitim-GC-jetanizeru-FID.jpg" alt="ARC: CO₂ analysis from 1ppm to 100% with GC/Jetanizer/FID"/>
<h3>Why is it important?</h3>
<h4>Low-level detection of CO and CO₂ is important in:</h4>
<ul>
<li>catalysis </li>
<li>hydrogen (H₂) purity analysis </li>
<li>dissolved gas analysis (DGA)</li>
<li>greenhouse gas (GHG) analysis, </li>
<li>transformer oil gas analysis (TOGA)</li>
<li>ethylene/propylene monomers analysis </li>
<li>safe entry analysis, and more</li>
</ul>
Traditionally, large nickel-catalyst-filled tube methanizers are used, however, they are prone to frequent failures, and they are difficult and time consuming to operate and maintain. 
<blockquote>
Legacy nickel catalyst methanizers take 2-6 hours to install and replace. Jetanizers take &lt;5 minutes.
</blockquote>
ARC’s Jetanizer solves these challenges by improving response, robustness and ease of installation, by incorporating state-of-the-art catalysts into an FID jet. Moreover, the Jetanizer enables low level &lt;1 ppm formaldehyde analysis by GC avoiding the pitfalls of HPLC analysis of formaldehyde.
<blockquote>

<h3>Why should I use GCxGC?</h3>
The separation of compounds by gas chromatography is typically performed using a single analytical column. As samples become more complex, it can become difficult to separate all the compounds from each other and they can start to overlap, or co-elute. Longer or narrower columns can be used to increase resolving power, but with diminishing returns.
Comprehensive two-dimensional GC, or GCxGC, drastically increases separation power by adding a second analytical column after the first column. A modulator placed between the two columns pulses the analytes from the first column onto the second column. When the columns are orthogonal in separation power, this technique can result in an order of magnitude increase in the number of analytes that can be detected.
ARC’s solution takes advantage of stop-flow modulation to make GCxGC an attainable configuration for any analytical laboratory. It involves continually sampling the effluent from the first column into an accumulator tube and re-injecting it onto a second, smaller column with orthogonal separation. This second separation happens in the time it takes to accumulate the next sample. The pulse time is known as the modulation time.

ARC Precision Split

ARC’s PrecisionSplit device allows scientists and chromatographers to take advantage of the quantitative power of the Polyarc/FID in combination with the mass identification power of the mass spectrometer, all in the same injection in real time.

<h3>Why does my MS need an FID?</h3>
A mass spectrometer (MS) provides valuable qualitative data, but poses several challenges to accurate quantification. Adding a flame ionization detector (FID) in parallel with the MS gives complementary quantitative carbon concentrations with minimal extra effort or equipment. We believe every MS needs an FID companion for quantitative analysis, especially for non-targeted analysis or tentatively identified compounds where quantification is desired.
<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/ARC_Precision_Split_6271ed1240/ARC-Precision-Split.jpg" alt="ARC: Precision Split"/>
<h3>The benefits of a MS/FID split:</h3>
<ul>
<li>Virtually eliminate response factor variability</li>
<li>Quantify accurately (better linearity, more consistent response, fewer calibration errors)</li>
<li>Improve sensitivity for poor ionizers with the FID</li>
<li>Save your source!</li>
</ul>
<h3>The Data</h3>
Response factor (RF) variation in the mass spectrometer (i.e., the relative response of the MS to different chemicals) can lead to significant errors in quantification. Two compounds that have the same response/area in the MS can have concentrations that differ more than 100-fold (see <a href="https://www.sciencedirect.com/science/article/pii/S0731708520304283">Jordi et al.</a>). 
As you can see below, the Polyarc/FID split can reduce this response factor variation so that accurate quantification of tentatively identified compounds is possible.
