“ Inject sample 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 a dangerous fire and explosion hazard (flash point = -30 °C) ; work with it only in a hood. SAMPLING: 1. 2. 3. 4. Calibrate each personal sampling pump with a representative sampler in line. Remove cassette plugs immediately before sampling. Attach sampler to personal sampling pump with flexible tubing. Sample at an accurately known flow rate between 1 and 3 L/min for a total sample size of 10 to 200 L. Cap the samplers with the cassette plugs and pack securely for shipment. SAMPLE PREPARATION: 5. 6. 7. ”
