This method is for the determination of ethyl chloride. The sample is collected on charcoal sorbent tubes, desorbed in carbon disulfide, and analyzed by GC/FID. The working range is 330 to 5300 mg/m³ (130 to 2000 ppm) for a 3 L air sample. Lower concentrations may be measured if desorption efficiency from the charcoal tube is adequate. NOTE: This method revises Method S105.
