Summary

This paper describes the sampling of air and its analysis for mixtures of organic solvent vapours by personal and room air samplers. The application of a potassium carbonate to remove water vapour, and silica gel adsorption tube cooled by dry ice for collection of organic solvents were investigated. The development of a method for the extraction of organic solvents from silica gel by cumene, ethyl ether, pyridine and dimethyl sulfoxide and subsequent estimation of their amounts by gas chromatography or colorimetry is reported. This method was useful for the personal air sampler in the workshop using thinner. Ethyl cellosolve acetate, and N,N-dimethyl formamide being cooled by dry ice and mixture of dimethyl sulfoxide and N,N-dimethyl formamide being cooled by ice were useful as absorbing agents of organic solvents particularly in the room air sampler.
