This method is for the determination of propylene oxide. The sample is collected on coconut shell charcoal tube, desorbed with carbon disulfide, and analyzed using GC/FID (flame ionization dectector). The working range of the method is 8 to 295 ppm (20 to 700 mg/m³) for a 5L air sample. NOTE: This method revises Method S75.
