Comprehensive VOC profiling of meat using dynamic headspace and automated TD–GC–MS analysis
20 Jan 2020This study shows that data acquired using the Centri® automated multi-mode sampling and preconcentration system for gas chromatography–mass spectrometry (GC–MS) can be used to generate useful insights into the aroma profiles of foods. In the example investigated, the dynamic headspace profiles of two cuts of lean steak were sampled at elevated temperature onto sorbent tubes, with subsequent preconcentration on Centri. Over 140 VOCs and SVOCs from a variety of chemical classes were identified, with the detection of a range of sulfur species demonstrating the inertness of the Centri flowpath and the use of optimised sorbent tubes and desorption conditions.

Gas ChromatographyGas chromatography (GC) is an analytical technique used to separate and quantitate mixtures of small and volatile compounds. Gas chromatographs or GC systems include components such as GC columns, detectors, pumps and autosamplers. Choose from packed or capillary GC columns, flame ionization (FID), photoionization (PID) electron capture detectors and selective or non-selective detectors.
