Dynamic Headspace-Gas Chromatography

Dynamic Headspace-Gas Chromatography is primarily used to analyze for the presence of volatile organic compounds in solid samples. While this analysis is more sensitive than static headspace the technique may be used for qualitative analysis, static headspace method development, or detection of trace levels of impurities, contaminants, or hazardous compounds. The analysis is conducted by first placing the sample into an open glass tube in a chamber heated to a desired temperature for a fixed time and purged with an inert gas. The volatiles are directed either onto an adsorbent trap or cryogenically focused on the head of a GC column and analyzed by gas chromatography/mass spectrometry (GC/MS). Our chemists have extensive knowledge and experience performing dynamic headspace analysis.

Test requests that normally result in the utilization of dynamic headspace include:
  • Identification of volatile organic compounds
