COLUMN:
stainless steel, 3.2-mm ID × 3 m, packed with 10% FFAP on 80/100 mesh Chromosorb W-AW DMCS
CALIBRATION:
standard solutions of n-butyl glycidyl ether in CS2
RANGE:
1.6 to 6.4 mg per sample
2 to 10 field blanks per set ACCURACY
RANGE STUDIED:
133 to 542 mg/m³ [1] (10-L samples)
BIAS:
−16.1% @ 133 mg/m³ [1] −1.0% @ 259 to 542 mg/m³
OVERALL PRECISION ( ): 0.074 [1]
ESTIMATED LOD: not determined ACCURACY:
±15.5% @ 259 to 592 mg/m³ ±30.6% @ 133 mg/m³
PRECISION ( ):
0.016 [1]
APPLICABILITY: The working range is 15 to 60 ppm (80 to 320 mg/m³) for a 20-L air sample. Because of unexpected bias at the lowest test level and the possibility of poor desorption efficiency at low loadings, a sample volume of at least 15 L is recommended. This method has not been evaluated for short-term exposures at 5.6 ppm. An appropriate capillary column may be used for better resolution and sensitivity. INTERFERENCES: None identified. OTHER METHODS: This is Method S81 [2] in a revised format.
