Method 109

Isopropyl alcohol

This method is for the collection and analysis of isopropyl alcohol. Samples are collected by drawing a known volume of air through two 8-mm o.d. (6-mm i.d.) Anasorb® 747 tubes in series. The front tube contains 400 mg of adsorbent, and the back tube 200 mg. Samples are desorbed with a 60/40 N,N-dimethylformamide/carbon disulfide solution and analyzed by GC using a flame ionization detector (FID). The air sampler must be separated into its component sampling tubes as soon as possible after sampling. This will prevent post-sampling migration.
