The pyrolysis–GC–MS method enables direct analysis of solid or liquid polymers without sample pretreatment, as illustrated here for various materials, including a dental filling material and a car wrapping foil.

Have you wondered how your GC system sets and controls gas pressures, flows, and carrier gas velocities electronically? Here, we describe the requirements for and the operation of electronic gas control systems for GC columns and detectors.

In this instalment, guest authors Jeff Hurst and Kendra Pfeifer from Hershey Foods explore high performance liquid chromatography (HPLC), ultrahigh-pressure liquid chromatography (UHPLC), and mass spectrometry (MS) approaches being adopted to keep ahead of the food adulteration game.
