During volatile analysis, samples are purged with an inert gas in order for the Volatile Organic Compounds (VOCs) to be swept out of the sample and onto an analytical trap. Purge flows and times are recommended by the United States Environmental Protection Agency (USEPA). For years the USEPA recommended purge flow and time was 40ml/min for 11 minutes, however in USEPA Method 524.3 and 4 there is approval to vary purge flows and times.
