Scientists in China have devised a GC-ECD procedure that involves bromination of acrylamide to give a derivative that is more easily detected at low levels than acrylamide itself. Their research comes in response to the discovery of acrylamide in many types of cooked food in 2002. This discovery made news due to the link between acrylamide and cancer. From a scientific point of view, the acrylamide discovery ensured the creation of a new generation of research grants, many of which involve mass spectrometry, using GC?MS or LC?MS.
