The US Environmental Protection Agency (EPA) developed a method for the analysis of semivolatiles using GC-MS/MS. This method allows the determination of on-column amounts of target compounds to be detected at orders of magnitude lower concentrations than conventional single quadrupole mass spectrometers. New column requirements include enhanced robustness, thermal stability, improved PAH selectivity, and extended lifetime following highly contaminated extracts. This presentation will show specific weaknesses of general-purpose 5-type columns for the analysis of environmental samples and the advantages of this new Rxi-SVOC column when used with tandem mass spectrometers.

Jaap is a world-renowned chromatographer with over 40 years of experience, including 15 years with Restek and 27 years with Varian/Chrompack prior to joining Restek. Throughout his career, Jaap has focused the chromatographic challenges of industrial analysis. For his 1979 graduation from The Institute for Higher Education, where he specialized in chemistry, Jaap authored a paper titled "The Challenge of Coating Flexible Fused Silica Capillary Columns" and has since distinguished himself as an authority on the subject. Jaap has been directly involved with the creation of numerous chemically bonded columns, including the first bonded PEG column and the stabilized PLOT columns widely used in the petrochemical arena. He has also helped develop new techniques, such as fast GC-MS using vacuum GC technology (low-pressure GC or LPGC). Over his innovative career, he has filed several patents for his work. Based out of the Netherlands, Jaap is extensively published and regularly travels internationally to share his knowledge. After retiring from Restek, Jaap founded CreaVisions, where he works as a GC Consultant and teaches master classes on key GC topics as well as on creativity in science.
