CALIBRATION:

standard solutions of allyl chloride in benzene

RANGE:

0.05 to 1.5 mg per sample

2 to 10 field blanks per set ACCURACY

RANGE STUDIED: BIAS:

1.8 to 7.2 mg/m³ [1] (100-L samples) 6.4%

OVERALL PRECISION :	0.071 [1]

ESTIMATED LOD:	 0.01 mg per sample ACCURACY:

±16.6%

PRECISION :

0.023 [1]

APPLICABILITY: The working range is 0.16 to 3 ppm (0.5 to 10 mg/m³) for a 100-L air sample. The method is applicable to short-term samples taken at 1 L/min. The upper limit of loading depends on the concentrations of allyl chloride and other substances in the air, including water vapor. INTERFERENCES: None identified. OTHER METHODS: This is Method S116 in a revised format [2].
