This method is for the determination of propoxur (Baygon) from workplace air. The sample is collected using an OVS-2 tube which consists of a glass fiber filter and two sections of XAD-2 absorbent. The samples are extracted with acetonitrile and analyzed by high performance liquid chromatography (HPLC) using an ultraviolet (UV) detector.
Note: This method has been only partially validated by OSHA.
