<abstract displayLabel="Summary">The application of high-performance liquid chromatography on a silica gel phase has resulted in amethod for analysis of dimethyl formamide, methylene bisphenyl isocyanate and methylene bisphenyl amine in air samples. The above mixture was used in the production of polyurethane fibres. For sampling purposes, silica gel coated with diethylamine was used. Since isocyanate is highly reactive, it must be rapidly converted into a stable derivative. This was achieved by reaction with diethylamine. After desorption of the mixture, compounds are separated by high-performance liquid chromatography. Spectrophotometric detection was used for quantitative determination of the mixture components</abstract>
