“ Carbon disulfide is toxic and an acute fire and explosion hazard (flash point = -30 °C) ; all work done with it must be performed in a fume 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 25 L. Cap the samplers with plastic (not rubber) caps and pack securely for shipment. ”

“ This method was developed to give better desorption than obtainable with carbon disulfide extraction of the charcoal. This method can be used in paint and resin manufacturing plants.
INTERFERENCES: None reported. Alternate columns, e.g., 4 m 10% SP-2100/0.1% Carbowax 1500 on Supelcoport 100/120 or DB-1 fused silica capillary may be used.
OTHER METHODS: This method combines and replaces Methods S10, S12, S13, S15 and S16 [1] .
