| Definition | US EPA 624 - Purgeables by GC/MS. Determination of purgeable organic pollutants in industrial discharges and other environmental samples by gas chromatography combined with mass spectrometry (GC/MS). A sample is purged with an inert gas transforming the purgeable organics to the vapor phase where it is collected on an absorbent trap at ambient temperature. After the sample is purged, the trap is then heated, backflushed, and desorbed with the inert gas onto an chromatographic column. The gas chromatograph is temperature programmed to separate the purgeable organics, which are then detected by a mass spectrometer (MS) |
