Hot Topics in Gas Chromatography

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.

We take a look at the past, present, and future of applying gas chromatography–mass spectroscopy (GC–MS) techniques to non-targeted screening (NTS) in various disciplines, assessing both the opportunities and the challenges.

Recycling plastics involves catalytically cracking polymers back into their constituent monomer mixtures, which require careful characterization for further processing. There is a resurging need for detectors that can detect and characterize heteroatom-containing species.

Correlation, clustering, and color projection techniques exploit the ability of the human brain to identify patterns from huge amounts of visual information. This process can provide a life raft for a weary chromatographer who is drowning in data.

Microextraction is an affordable solution for preventing “garbage in–garbage out” effects in one-dimensional (1D) and two-dimensional (2D) GC separations, by providing analyte preconcentration, interference removal, tuning of extraction coverage, and easy coupling to GC systems.
