Analytical Challenges and Strategies for Compound Identification Using Gas Chromatography–Ion Mobility Spectrometry

<p><strong>Measurement results are only fit for purpose if the measurement uncertainty (MU) is reliable and has a magnitude small enough for the intended use. The target MU is the maximum admissible uncertainty defined for a specific measurement goal.&nbsp;</strong></p><p>In compliance assessment, the MU should be small enough to enable identification of deviations from compliance relevant to the interests to be protected (such as public health or industrial productivity). Too large an uncertainty would not provide the required protection, while an uncertainty that is too small could mean the use of unnecessary expensive measurements.&nbsp;</p><p>The Eurachem/CITAC guide on ‘<i><strong>Setting and Using Target Uncertainty in Chemical Measurement</strong></i>’ suggests how to set upper boundaries for the uncertainty based on the intended use of the result [1].&nbsp;</p><p><strong>The impact of the MU on decisions is illustrated in a fictional scenario.&nbsp;</strong></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Setting_Target_Measurement_Uncertainty_2_daf2cb4ec8.jpg" alt="Eurachem: Setting Target Measurement Uncertainty" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Setting_Target_Measurement_Uncertainty_2_daf2cb4ec8.jpg 150w," sizes="100vw" width="740" height="770"></p><p>Mr. Reis is a farmer planning to sell oranges to a juice producer. The juice producer checks oranges for thiabendazole pesticide residues and Brix level (degrees Brix provides a measure of orange juice sweetness). The producer only accepts oranges with thiabendazole residues below 1 mg kg<sup>-1</sup> and a Brix level above 55 °Bx, paying more if the Brix level is above 65 °Bx.&nbsp;</p><p>Mr. Reis contracted Laboratory C to analyse his oranges before shipping them to the producer knowing that the customer also checks the oranges in its laboratory. Mr. Reis was very happy with the results provided by Laboratory C although the pesticide residue analyses were expensive.&nbsp;</p><p>The producer accepted the oranges but decided to pay less than expected.&nbsp;</p><p>After asking the juice producer, the detailed results of both laboratories were compared. This showed that although the results were metrologically compatible they supported different decisions on the oranges’ price.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Setting_Target_Measurement_Uncertainty_3_aa7c28e61a.jpg" alt="Eurachem: Setting Target Measurement Uncertainty - Laboratory C" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Setting_Target_Measurement_Uncertainty_3_aa7c28e61a.jpg 245w," sizes="100vw" width="927" height="192"></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Setting_Target_Measurement_Uncertainty_4_4588f40881.jpg" alt="Eurachem: Setting Target Measurement Uncertainty - Juice producers Laboratory" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Setting_Target_Measurement_Uncertainty_4_4588f40881.jpg 245w," sizes="100vw" width="911" height="195"></p><p>The measurement of thiabendazole residues performed by Laboratory C is associated with an extremely low uncertainty making measurements more expensive than necessary. However, the uncertainty associated with the determination of the Brix level is too large, making compliance decisions too uncertain.</p><p>Measurement results are only fit for the intended use if the measurement uncertainty (MU) is smaller than a maximum acceptable value (i.e. the target MU).&nbsp;</p><p>Even if the customer or the regulator does not define the target MU, the laboratory should define it to decide if the measurement is fit for the intended use. The Eurachem/CITAC guide [1] suggests the use of different indicators of the measurement quality requirement to define the target MU. Information used to define the target MU is presented from the most likely to become harmonised to the ones supported with less adequate data. The following figure presents this hierarchy of adequacy with numbers from #1 to #9.</p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Eurachem_Setting_Target_Measurement_Uncertainty_01cd73bb2c.jpg" alt="Eurachem: Setting Target Measurement Uncertainty" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Eurachem_Setting_Target_Measurement_Uncertainty_01cd73bb2c.jpg 245w," sizes="100vw" width="1600" height="900"></p><blockquote><p>Approaches to defining the target MU described in the Eurachem/CITAC Guide, where u<sup>tg</sup> and U<sup>tg</sup> represent the target standard and expanded uncertainties, respectively.

While the wide range of commercially available stationary phase chemistries provides extensive opportunities to optimise selectivity, navigating these choices can be challenging, often leading to suboptimal column selection and missed opportunities to improve separation performance or speed of analysis.</p><p>This seminar will explore why stationary phase selectivity is one of the most powerful tools available to chromatographers for method development. Approaches for characterizing selectivity, including the Tanaka and Neue methodologies, will be discussed as practical tools for understanding and differentiating column chemistries. These concepts will then be used to demonstrate how stationary phase design can be rationalized and how a deeper understanding of selectivity can guide more effective column selection.</p><p>Application examples will highlight the impact of stationary phase chemistry across a range of analytes, including small molecules and peptides. The seminar will also examine how rational stationary phase selection can be incorporated into streamlined workflows for reversed-phase LC, HILIC and SFC method development.</p><p>Attendees will gain a deeper understanding of how strategic column selection can enhance resolution, reduce method development time, and enhance overall method performance. The concepts presented will provide a practical framework for scientists seeking a more structured, efficient, and knowledge-driven approach to method development.</p><blockquote><p><strong>Dr Matt James</strong></p><p>Matt James is a Senior Research Scientist at Avantor Sciences.

However, the benefits of the particle with the solid silica core surrounded by the porous silica shell were not realized for small molecules until 2006 when the first sub-3-µm superficially porous particle columns were introduced. This particle technology enabled efficiencies similar to sub-2-µm fully porous particles (FPPs) without the need for ultra-high pressure capable instrumentation. As a result of the high efficiencies and lower back pressure, the columns may be run at faster flow rates to enable high throughput separations. Additionally, the SPP columns are rugged and offer long column lifetimes. This presentation will highlight comparisons between SPP columns and FPP columns for separations of pharmaceuticals, pesticides, and oligonucleotides.</p><h4><strong>Lunch seminar Restek</strong></h4><h5><strong>Virtual Chromatographic Modelling Software For Optimising Separation Of Isobaric Compounds in GC-MS Methods</strong></h5><ul><li><strong>Sebastian Prisacariu, Anna Pulte</strong></li><li>Tuesday, 8 September 2026&nbsp;</li><li>13:00-14:00</li><li><strong>👉</strong><a target="_blank" rel="noopener noreferrer" href="https://form.jotform.com/262112099571355"><strong>REGISTER HERE</strong></a></li></ul><p>There is a constant balance for high-throughput laboratories between method run times for large panel analyses and resolution of analytes across these panels to allow sufficient data quality. Developing such methods is often time consuming and expensive for laboratories, as dedicated resources are required to test methods iteratively. Chromatographic modelling tools are becoming increasingly popular for method setup and refinement in high-throughput laboratories looking to minimise instrument and analyst downtime. These tools traditionally offer column phase and method condition suggestions based on the separation of a list of analytes, which can then be modified to improve specific separations as necessary.</p><p>When developing gas chromatography (GC) methods, shortening cycle time often comes at the cost of compounds co-eluting, with the expectation that a mass selective detector, such as a mass spectrometer (MS) will allow resolution through ion-selective quantitation. An issue arises when the method attempts to analyse isobaric compounds, which cannot be distinguished by MS, and as a result labs must rely upon physical separation via column phase chemistry.</p><p>As GC-MS techniques continue to be adopted by laboratories, there is a need for more tools that consider mass data for analytes when optimising large panel separations. The virtual chromatographic modelling tool used in this study is built with mass spectrum data for compounds included in libraries. When operating in “MS mode”, the software identifies isobaric compounds and prioritises their separation when making recommendations regarding column phase and method conditions. For those using non-mass selective detection methods, the tool is easily toggled to “FID mode” for users interested in resolving all compounds, regardless of specific mass, allowing for flexibility in instrumentation. Results help labs save time and resources in method development and refinement by considering the instrumentation involved in the model.</p><h4><strong>Lunch seminar Thermo Fisher Scientific</strong></h4><h5><strong>ASOs, ADCs, and Other Therapeutics: Advanced Characterization with Novel Reversed-Phase Columns and Integrated LC–MS Platform</strong></h5><ul><li>Tuesday, 8 September 2026&nbsp;</li><li>13:00-14:00</li><li><strong>👉</strong><a target="_blank" rel="noopener noreferrer" href="https://forms.cloud.microsoft/pages/responsepage.aspx?id=LXJ9toqqd0ehaevremo7Zz9X1b58h7ZKmlE1n_EPKh5URFJOMFFMVlZWOEc2NUQzWUlTTVY2UEhSTy4u&amp;route=shorturl"><strong>REGISTER HERE</strong></a></li></ul><p>Biotherapeutics are becoming increasingly structurally diverse, placing greater demands on analytical platforms that can support efficient development and regulatory readiness. Reversed-phase chromatography (RPC) remains a widely adopted and adaptable technique, supporting applications that range from oligonucleotide analysis to detailed protein characterization and post-translational modification assessment.</p><p>This seminar explores the integration of a macroporous, monodisperse reversed-phase column with a next-generation bioinert LC system for the analysis of two emerging classes of biotherapeutics. Antisense oligonucleotides were examined under optimized chromatographic conditions, using a design-of-experiments strategy to evaluate how ion-pairing reagents influence both LC separation and downstream MS performance. The platform was further applied to antibody–drug conjugates, combining RPC with Orbitrap mass spectrometry to support multi-level characterization. Intact, sub-unit, and bottom-up analyses enabled drug-to-antibody ratio determination alongside detailed PTM profiling — including glycosylation, oxidation, and deamidation — under native and stress conditions.
