[Quantitative method of toluol diffusive sampling].

The diffusive sampling is of great advantage to air pollutant monitoring in manned spaceflight cabin. The quantitative method and steps of diffusive sampling is given in this paper by an experimental studying on diffusive sampling of toluol-air mixture; Effectiveness of the method and effects of environmental factors on the quantification of the diffusive sampling were discussed. This method is of reference value to quantification of the polycomponent-air mixture.
