In this instalment we take a close look at Golay’s famous equation that most people see as relating HETP (height equivalent to a theoretical plate) to the carrier gas flow rate or average linear gas velocity in a capillary column.

We are all familiar with Golay’s equation relating to height equivalent to a theoretical plate (HETP) in GC. But do we understand it correctly?

How can we make our workflows more efficient, our detection limits lower, and our instruments cleaner?

Gas chromatographers may not have the latest equipment they need. Here, we give a list of tools and consumables that can help make workflows more efficient, detection limits lower, and GC instruments cleaner.

Professor Harold Monroe McNair, among the original icons of chromatography, passed away on 27 June 2021 at the age of 88. In this tribute to the remarkable man and using his works as a guide, we explore three fundamental areas of understanding in GC, seeing ideas about problems that still challenge gas chromatographers today.

The late Harold McNair had a remarkable 60-year career as a chromatographer. He taught us many valuable lessons, three of which we discuss here.
