title: Evaluation of charcoal sampling tubes.
abstract: The effectiveness of MSA charcoal tubes and those constructed by the USAF Environmental Health Laboratory were statistically compared. No significant differences were noted. Also, tube recovery efficiencies were determined for 10 different solvents for which there was no or limited data. The effects of moisture on gravimetric analysis are presented.
