UV spectroscopy is an effective approach for tandem or parallel detection in gas chromatography, particularly in separations that require narrow bandwidths, such as GCxGC.

The incorporation of a post-column reaction using a 3D-printed, two-stage microreactor is showing groundbreaking performance improvements for flame ionization detection in many gas chromatography applications—and delivers carbon universal response.

A highly sensitive and selective mercuric oxide–based reduction gas detector was successfully used for parts-per-billion level gas chromatography (GC) determination of ethylene in various matrices such as in the monitoring of fruit ripening, ambient air, and industrial solvents.

Pulsed-flow-modulated comprehensive two-dimensional gas chromatography with flame ionisation detection was used to separate and identify all common sulphur compounds found in natural gas.

A practical and reliable analytical procedure that incorporates MDGC with a planar microfl uidic device as a Deans switch was developed for the characterization of chlorinated degreasers in marine gas oil.

A method able to quantitate odorants at levels as low as 100 ppb (v/v)
