Dynamic headspace analysis

{
  "id": "MLC-T-CHM-003492",
  "term": "Dynamic headspace analysis",
  "field": "Chemistry",
  "definition": "A technique for analyzing volatile compounds in a sample by continuously sweeping an inert gas through the headspace above the sample, trapping the volatilized analytes onto a sorbent material. The trapped analytes are then desorbed and introduced into a gas chromatograph for separation and detection. This method offers higher sensitivity than static headspace analysis due to the continuous removal of analytes from the headspace.",
