Recent advances in coating techniques and improved polymers employed as gas chromatographic stationary phases have resulted in commercializing low phase ratio capillary column technology with respectable chromatographic efficiency and inertness.

Two-dimensional LC, with advanced modulation techniques, can advance the analysis of advanced polymeric materials, assisting in characterizing copolymer composition heterogeneity and identifying ingredients in complex products.

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)

A review of a gas chromatographic procedure developed for the direct measurement of trace levels of lindane, aldrin, heptachlor epoxide, dieldrin, o,p-DDD, and dichlorodiphenyltrichloroethane (DDT)
