LCGC TV: Gas Chromatography

February 11th 2015

Comprehensive gas chromatography (GC) is a multidimensional technique that has the potential to increase peak capacity resolution when separating complex mixtures. In this new video from LCGC TV, Luigi Mondello from the University of Messinia, Italy, describes the fundamental principles of 2D GC, and explains the advantages over 1D GC.

Thermal gradient gas chromatography (TGGC) was first developed in the 1960s to reduce the effects of peak broadening. With recent developments in technology, the technique is now being re-examined. In two new videos from LCGC TV, Milton L. Lee from Brigham Young University discusses the principles of TGGC, and the possible advantages of TGGC over traditional GC methods.

Tom Brettell, an associate professor of chemistry at Cedar Crest College, USA, recently conducted a survey of gas chromatography column use in forensic laboratories in the United States. Here is what he found, in terms of the types of columns they are using and the problems they face.

When you are setting up a two-dimensional GC separation (GCxGC), how do you get the optimal combination of columns with the least amount of method development pain? In two new short videos, Nick Snow of Seton Hall offers advice, about column type and column length.
