APPLICABILITY: This method may be used to determine two or more analytes simultaneously by varying GC conditions (e.g., temperature programming).
INTERFERENCES: The methods were validated using a 3 m x 3-mm ID stainless steel column packed with 10% FFAP on Chromosorb W-AW; other columns with equal or better resolution (e.g., capillary) may be used.
OTHER METHODS: This method combines and replaces Methods S66, S53, S64 and S62 [3].
