Back in 2005 two Russian scientists Berezkin and Lapin [1] investigated the application of ultra-short capillary gas chromatography (GC) columns. Ordinary, the GC columns are extremely lengthy and range from 10 to 150 meters in order to achieve effective separation of mixed components. Berezkin’s earlier research [2] showed that 75% of all GC columns used in […]

Gas Chromatography (GC) is one of the primary analytical techniques used in every CSI laboratory.

Choosing the right column is key in Gas Chromatography. “Columns for Gas Chromatography: Performance and Selection” is a new hands-on reference for scientists and technicians working with packed column and capillary column gas chromatography. The authors Eugene F. Barry (University of Massachusetts Lowell) and Robert L. Grob (Villanova University) discuss the development, performance, selection, and […]
