Seminar: Unleash Your Performance with the Next Generation GC Column Technology for the GC-MS/MS analysis of pesticides in difficult food Matrices
Session Time and Location: Thursday 11 June 2026, 14:10 – 14:45 | Mees Room 1&2, Ground floor
Presenter(s)/Co-Author(s): Dr. Javier Arrebola, Colton Myers, Laura Schuetz, Alexander Zahm, Olivier Griffaton
Gas Chromatography is a proven technique for the analysis of pesticide compounds in food matrix. Recent changes in regulations including chlorinated solvent ban, method consolidation for pesticides methods, and reduced volume extraction, and sensitivity requirements has lead to a need for a GC solution that can meet and exceed the detection requirements. In addition, there is a need for matrix resilience and extended lifetime and continued calibration. This presentation will unleash how the latest column deactivation technology and unique formats in GC can address these challenges. Real and challenging food matrices were subjected to analytical testing to demonstrate robustness and resilience of the next generation GC Column, enhancing GC-MS/MS analysis of fruits, vegetables, cereals, and legumes in a high-throughput Laboratory.

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.

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.

A novel gas chromatography–mass spectrometry (GC–MS) column design has been developed to enhance analytical performance by addressing persistent challenges in baseline stability and sensitivity. This innovation integrates a unique interface configuration that minimizes stationary phase degradation and thermal stress effects, particularly under elevated transfer line temperatures. Comparative evaluations using a diverse panel of pesticide analytes demonstrated significantly faster baseline stabilization and reduced background noise relative to conventional columns.
The new column architecture consistently delivered improved signal-to-noise ratios across full-scan and SIM modes, with pronounced benefits observed for high-boiling-point and late-eluting compounds. These enhancements suggest a substantial reduction in analyte loss and column bleed, enabling more reliable detection of thermally labile substances. The findings underscore the potential of this design to advance GC–MS methodologies in trace-level contaminant analysis and complex sample matrices.
