BLANKS:

2 to 10 field blanks per set

COLUMN:

10 ft x 1/8-in. ID stainless steel column packed with 10% FFAP on 80/100 mesh, acid washed DMCS Chromosorb W

DETECTOR:

flame ionization detector

CALIBRATION:

standard solutions of phenyl ether in hexane

RANGE:

7 to 210 µg per sample [1,2]

ACCURACY RANGE STUDIED:

3.0 to 13.0 mg/m 3 [1] (10-L samples)

BIAS:

ACCURACY:

± 13.7%

ESTIMATED LOD: 0.7 µg per sample [1,2] PRECISION (Sr):

0.048 [1,2]

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].
