The Storage and Use of Gases for Gas Chromatography
March 1, 2014

This instalment discusses the storage and use of carrier and detector gases, gas filtration, and the means by which pressures are controlled on the way from the gas supplies to a GC instrument.

The Storage and Use of Gases for Gas Chromatography
March 1, 2014

A discussion on the safe storage and use of calibration, carrier, and detector gas cylinders for small or large organizations.

The Origins of GC Carrier Gases: Putting a Genie in the Bottle

We track the genesis of the top four carrier gases before they start their journey through a GC system.

The Origins of GC Carrier Gases: Putting a Genie in the Bottle
January 1, 2014

This month's instalment tracks the progress of helium, hydrogen, and nitrogen carrier gases as they start their journey through a GC system.

Practical Gas Chromatography
November 1, 2013

Questions about how practical proposed gas chromatography (GC) method changes are often come up during optimization for speed and resolution, or while converting to a different carrier gas. Related objective measurements such as the optimum practical carrier gas velocity were defined more than 40 years ago. This instalment reviews such metrics in the light of their relevance to today's GC challenges.

Practical Gas Chromatography
November 1, 2013

A discussion of the effects of increased carrier-gas flow in an example separation that includes two pairs of solutes.

How Do Your Peaks Measure Up?
October 1, 2013

The anatomy of chromatographic peaks is examined with attention to features that help determine the suitability of individual chromatographs for a specific analysis task.

A Long Distance Run
September 1, 2013

In this instalment, John Hinshaw compares the GC separation process to a long-distance run through a long corridor with some unique properties. The runners are separated in various ways.
