Safely Delivering the Best Possible Carrier and Detector Gases to Your GC System

The quality of a gas chromatogram depends heavily on the quality of the separation and detection gases, among many other factors. In this month’s instalment, “GC Connections” discusses ways in which chromatographers can ensure a safe working environment while delivering gases that are up to the requirements of the separations at hand, in the context of moving a laboratory to a new location.

A Compendium of GC Detection, Past and Present

Gas chromatography makes use of a wide variety of detection methods. In addition to the most often used flame-ionization detection (FID), electron-capture detection (ECD), thermal conductivity detection (TCD), and mass-selective detection (MSD), the list of other detection methods is long. They really shine when deployed properly, but their properties and applications can be a bewildering alphabet soup. This instalment presents a compendium of gas chromatography (GC) detection methods, both past and vanished as well as those that are current and relevant to today’s separation challenges.
