Packed Columns, and their Wide Applicability in Modern Gas Chromatography

30 years ago, my manager told me that in the year 2000 we would not sell packed columns anymore, as everybody would be using capillaries. We are now in 2020 and packed columns are still widely used. Though they offer a relatively low plate count, they do offer robustness, capacity, speed and flexibility.

Packed columns have also benefited from technologies developed primarily for capillary columns. For example, using high purity, bonded polymer phases and deactivation technologies for SS tubing, like Siltek/Sulfinert.

In this webinar we will focus on the reasons why packed columns are a good choice and we will discuss their unique characteristics.

Presenter: Jaap de Zeeuw (Gas Chromatography Specialist)

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.
