Tekmar LSC2 Purge and Trap/Varian 3400 GC with OI Analytical Tandem PID/ELCD. The EzChrom Elite Chromatography Data System for data acquisition and processing

EPA methods:

  • Methods 601 -  analysis of purgeable halocarbons
  • Method 602 - purgeable aromatics
  • Method 8021 – analysis of aromatic and halogenated volatiles


In Purge & Trap (dynamic headspace) analysis volatile organics from aqueous or non-aqueous matrices are concentrated into detectable by the GC levels (e.g., drinking water). Volatile organic compounds are removed from water matrices during purge and concentrated on the trap sorbent. The organics are subsequently eluted from the sorbent and injected into a GC for separation and detection.
