Phase Separation Science accommodates air samples that may cause vapor intrusion of contaminants into living or working spaces thereby impacting human health.

  • Indoor air quality
  • Ambient air
  • Subsurface gas
  • Soil gas

The primary method for determining the concentration of volatile organic compounds in air is Method TO-15 Determination of Volatile Organic Compounds (VOCs) In Air Collected In Specially-Prepared Canisters by Gas Chromatography (GC) Mass.
