Understanding how approaches to degassing have evolved is helpful for troubleshooting problems with pumps and detection.

A novel LC–MS/MS method, with a dual ESI and APCI source using simple solvent extraction for sample preparation, was validated for analysis of 102 pesticides and 5 mycotoxins regulated by Colorado state in dried hemp.

Although not as common as in HPLC, molecular spectroscopy can be used with GC as well.

This article provides a high-level overview of Current Good Manufacturing Practice (cGMP) regulations and related public quality standards.

LCGC spoke to Leandro Wang Hantao from the University of Campinas in São Paulo, Brazil, about his work investigating the influence of ion management parameters on the data produced by comprehensive gas chromatography–high-resolution mass spectrometry (GC×GC–HRMS) equipped with a fourier transform-orbital ion trap mass analyzer, and his investigation into employing channel occlusion for sample preparation in untargeted analysis in petroleomics.

Here, we preview the International Symposium on Hyphenated Techniques in Chromatography and Separation Technology (HTC-18), which will be held from May 28–31st 2024 in Leuven, Belgium.
