This method is used for the determination of n-butyl glycidyl ether. The sample is collected on charcoal sorbent tubes and desorbed with 0.5 mL carbon disulfide for 30 minutes. The sample is then analyzed by GC/FID (Gas Chromatography/Flame Ionization Detector). The working range is 15 to 60 ppm (80 to 320 mg/m³) for a 20 L air sample. Because of unexpected bias at the lowest test level and the possibility of poor desorption efficiency at low loadings, a sample volume of at least 15 L is recommended. This method has not been evaluated for short term exposures at 5.6 ppm. An appropriate capillary column may be used for better resolution and sensitivity. NOTE: This is Method S81 in a revised format.
