Technical Presentations
Seminar: Unleash Your Performance with the Next Generation GC Column
Presentation: Wednesday, May 20, 10:50a.m.-11:50 a.m. | Dolomiti Room
Author: Victoria Zeger, Advanced Scientist in GC Technologies at Restek Corporation
Gas chromatography (GC) is a well-established technique for the analysis of pesticides in food matrices. Recent changes in regulations, the consolidation of pesticide methods, reduced-volume extraction, and increased sensitivity requirements have led to a growing need for GC solutions that can meet and exceed detection limits.
In addition, there is a demand for improved matrix resilience, extended column lifetime, and stable calibration over time. This presentation will demonstrate how the latest column deactivation technologies and innovative GC column formats can address these challenges.
A range of real and challenging semivolatile compounds and pesticides were analyzed to demonstrate the robustness and resilience of next-generation GC columns, enhancing GC-MS/MS performance.
Poster: Simplifying PFAS analysis with an improved Dual Bed Solid-Phase Extraction Method

Per- and Polyfluoroalkyl Substances (PFAS) are synthetic organofluorine chemicals that have been linked to a range of health effects, including decrease immune response, vaccine effectiveness, cancer risk, among others.
In this work we show a comprehensive analysis of 40 target PFAS compounds in different aqueous, solids, and tissue matrixes. This method uses a weak anion exchange (WAX) solid phase extraction (SPE), coupled with a dispersive graphitized carbon black (GCB) clean-up step prior to LC-MS/MS analysis on a C18 column.
Poster: Importance of GC Columns Deactivation Technology for the Analysis of Challenging Analytes
Authors: Sandra Ruiz Perez2, Victoria Zeger3, Erika Pack3, Chris English3, Ramkumar Dhandapani3
A recent advancement in gas chromatography (GC) column deactivation balances chromatographic performance of acidic, basic and neutral analytes at trace level concentrations. Deactivation is a critical step in GC column manufacturing that modifies the fused silica capillary surface activity to promote coating and adhesion. Residual surface silanols, which result from incomplete deactivation or surface contamination, adsorb acidic and basic compounds resulting in peak area loss or tailing.
Deactivation procedures vary between products and manufacturers, with individual benefits and drawbacks that become exacerbated during sensitive applications. There is increasing demand to improve identification and quantification of reactive analytes with complex or consolidated methodologies. New GC deactivation technology improves polymer adhesion and minimizes residual surface activity for a long lasting, broadly inert surface. Columns built with the new GC deactivation technology were challenged with a wide variety of applications, and against traditional 5-type columns.
Overall, the new deactivation presents an advancement over traditional GC columns, providing unparalleled inertness to a broader range of acids, bases, and neutrals. These improvements offer opportunity for method consolidation and trace level analysis that would not be successful with traditional technology.
