This method is for the determination of ethyl bromide. The sample is collected on charcoal sorbent tubes, desorbed in carbon disulfide, and analyzed using GC/FID. The working range is 22 to 560 ppm (100 to 2500 mg/m³) for a 4 L air sample. Ethyl bromide is used in organic synthesis as a solvent and as a refrigerant, anesthetic, and grain and fruit fumigant. Note: This method revises Method S106.
