title: [Sampling of solvents on active charcoal: chemical and thermal recovery].
abstract: The problems relating to the sampling of solvents on active charcoal and their recovery by chemical and thermal desorption are pointed out. The experimental values of breakthrough volumes for a number of compounds are reported, together with their extent of recovery by carbon disulfide extraction and by thermal desorption under inert gas flow. Thermal desorption, when carried out under the proper conditions, including the use of a temperature program, leads to quantitative recovery for most industrial solvents.
