APPLICABILITY: The working range is 0.1 to 9 ppm (0.7 to 60 mg/m 3) for a 10-L air sample. Better sensitivity may be achieved with a capillary column with appropriate adjustment in the instrumental conditions. A DB-wax (polyethelyene glycol) or e quivalent is similar to the FFAP packed column.
INTERFERENCES: None identified.
OTHER METHODS: This revises Method S72 [3].
