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.
