This method is for the collection and analysis of benzophenone from workplace air. The sample is collected on a Chromosorb 106 tube. After collection, the sample is extracted with a solution of carbon disulfide/N, N-dimethylformamide (99:1) and analyzed by GC/FID (flame ionization detector).
NOTE: Ths is a partically validated method.
