“ ESTIMATED LOD: 0.01 mg per sample [2]
± 20%
APPLICABILITY: The working range is 1 to 10 mg/m 3 for allyl alcohol (other analytes range from 45 to 140 mg/m 3 at low end and 175 to 680 mg/m 3 at high end of working ranges) for a 10-L air sample. This method may be used to determine two or more analytes simultaneously by varying GC conditions (e.g., temperature programming) .
INTERFERENCES: High humidity reduces sampling capacity. The methods were validated using a 3 m x 3-mm stainless steel column packed with 10% FFAP on Chromosorb W-AW ”

“ Inject sample aliquot manually using solvent flush technique or with autosampler. NOTE: If peak area is above the linear range of the working standards, dilute with eluent, reanalyze and apply the appropriate dilution factor in calculations. Measure peak area. Divide the peak area of analyte by the peak area of internal standard on the same chromatogram. ”

“ Carbon disulfide is toxic and an acute fire and explosion hazard (flash point = -30 °C) ; all work with it must be done in a hood.
SAMPLING: 1. 2. 3. 4.
Calibrate each personal sampling pump with a representative sampler in line. Break the ends of the sampler immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. Sample at an accurately known flow rate between 0.01 and 0.2 L/min for a total sample size of 1 to 10 L. Cap the samplers with plastic (not rubber) caps and pack securely for shipment. ”
