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 ( ):

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].
