Reduction of analysis time in GC using existing instrumentation

There a number of ways that the analysis time can be reduced. All depends on how well the components are separated in the present application.

• Most easy is to trade in some resolution for speed using higher gas velocities or using a shorter column.
• If the exact separation must be maintained, a choice has to be made between using hydrogen as carrier gas, or use a smaller ID capillary column (or a combination).
• Important is that in the new method, the same chromatogram must be obtained. Using the EZGC method translator, you can simply calculate the oven program you need for that.

Also the ProEZGC chromatogram modeler, you can see the impact of any changed parameter, using your computer.

Presenter: Jaap de Zeeuw (Gas Chromatography Specialist, Restek)

Jaap is a world-renowned chromatographer with over 40 years of experience, including 27 years with Varian/Chrompack focusing on industrial analysis challenges. For his 1979 graduation from The Institute for Higher Education, 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. 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, Restek’s international GC specialist has helped develop new techniques, such as fast GC-MS using vacuum GC technology, and has filed two patents for his work. Based out of the Netherlands, Jaap celebrates 10 years with Restek. Jaap is extensively published and regularly travels internationally to share his knowledge.
