Detection of ethylene oxide in medical equipment by headspace-trap with multi-step enrichment and GC-MS

Levels of residual ethylene oxide remaining on medical equipment after sterilization are usually measured by extraction with water, but subsequent methods to analyze that water lack sensitivity.

Explore an alternative method that uses the focusing trap of Centri 90 to extract multiple large (5 mL) headspace volumes from a single water sample and analyze these together in one run. Discover how this method is fully automated and highly sensitive, to achieve a detection limit of 0.35 µg/L from water.
