This method is for the collection and analysis of alcohols by GC/FID (flame ionization detector). The alcohols evaluated in the method are: n-butyl alcohol, sec-butyl alcohol, isobutyl alcohol, and n-propyl alcohol. The sample is collected on a charcoal tube. After collection the sample is desorbed in 1mL of 1% 2-propanol in carbon disulfide and analyzed by GC/FID.
NOTE: This method combines and replaces Methods S66, S53, S64, and S62.
