Title: Analysis of selected gaseous organic micro-pollutants in air by means of solid phase microextraction-gas chromatography-mass spectrometry. Calibration problems
Abstract: In this work, problems related to calibration of solid phase microextraction (SPME) device were described.The effects of humidity and temperature on organic pollutants sampling from gaseous matrices on a 100 µm PDMS coated SPME fiber were studied.Standard gaseous mixtures used in these studies were generated by the permeation method and humidified to known levels of relative humidity.The SPME-GC-MS based procedure was used to determine organic vapours (carbon tetrachloride, toluene, chlorobenzene, p-xylene and n-decane) in a laboratory air.Key wo rd s.Solid phase micro ex t raction -gas ch ro m at ograp hy -calibration -vo l atile organic air pollutants -mass spectrometry.
