Method 1600

Carbon Disulfide

This method is for the determination of carbon disulfide from workplace air. The sample is collected on a coconut shell charcoal tube and sodium sulfate drying tube. The drying tube can be kept attached during shipment to the lab. The drying tube is discarded and the charcoal tube is desorbed in toluene and analyzed by GC/Sulfur FPD (flame photometric detector). Better sensitivity may be obtained by using a higher sampling rate if high humidity is not present.

This method has been used extensively in the viscose rayon industry and at carbon disulfide production facilities. The working range of the method is 10 to 200 mg/m³ (3 to 64 ppm) for a 5 L air sample and is applicable to ceiling determination.

NOTE: This method revises Methods S248 and 1600 (2/15/84) and replaces P&CAM 179.
