Method PV2103


This method is for the collection and analysis of chloropicrin from workplace air.  The sample is collected on two XAD-4 tubes connected in series.  After collection, the sample is desorbed with ethyl acetate and analyzed by GC/ECD (electron capture detector).

NOTE:  This is a partially validated method.
