Evaluation of glass sampling tubes for industrial breath analysis
American Industrial Hygiene Association Journal
|January 1, 1978
Abstract:
The storage of halogenated hydrocarbons in breath and air samples in glass cylindrical tubes was investigated to determine procedures to achieve a representative breath sampling technique. The loss of solvent vapor concentration over a fixed time period was observed and postulated to result from non-reactive absorption. If considerations are made for adverse sampling conditions of moisture, temperature, and tube surface condition, glass tubes prove to be an acceptable container for breath samples.
