A selective chromatographic mass-spectrometric procedure was developed to determine of air styrene, phenol, and naphthalene in the concentration range of 0.001-0.05 mg/m(3), Analysis used preconcentration of the compounds oil a solid sorbent, followed by thermal desorption into the capillary column of a chromatograph. Qualitative and quantitative measurements of concentrations were carried out by the characteristics chosen for each compound. The maximum relative measurement error in 1-2-liter air sampling was +/-23% at a 0.95 significant confidence. The analytic procedure was tested on real objects.
