ESTIMATED LOD: 0.01 mg per sample [2]
± 20%
APPLICABILITY: The working range is 1 to 10 mg/m 3 for allyl alcohol (other analytes range from 45 to 140 mg/m 3 at low end and 175 to 680 mg/m 3 at high end of working ranges) for a 10-L air sample. This method may be used to determine two or more analytes simultaneously by varying GC conditions (e.g., temperature programming).
INTERFERENCES: High humidity reduces sampling capacity. The methods were validated using a 3 m x 3-mm stainless steel column packed with 10% FFAP on Chromosorb W-AW; other columns with equal or better resolution (e.g., capillary) may be u sed. Less volatile compounds may displace more volatile compounds on the charcoal.
OTHER METHODS: This method combines and replaces Methods S52, S55, S54, S58 and S60 [3].
