USEPA Method 524.2 has been used by laboratories for many years for the analysis of volatile organic compounds in drinking water by purge and trap concentration with detection using Gas Chromatography/Mass Spectrometry (GC/MS). This method requires an 11 minute purge at 40 mL/minute and a 4 minute desorb. The 4 minute desorb transfers a significant amount of water to the GC/MS, which has become more problematic as newer, more sensitive instruments are being used. Method 524.3 was released in 2009 and allows the user greater latitude when optimizing instrument and purge and trap parameters.
