Volatile organic compounds were personally sampled by people classified as cases (people having certain SBS symptoms) and controls, i.e. people not fulfilling the criteria's for cases. The aim of the study was to find out which adsorbent that gave the best separation between SBS cases and controls based on their chemical exposure of VOCs. The statistical method used was partial least squares discriminant analysis (PLS-DA). The adsorbents compared were Carbopack B, Chromosorb 106 and Tenax TA. The study included 30 office workers wearing diffusive samplers during one working week. The samplers were analysed with thermal desorption-GC-MS, and each chromatographic peak was included in the data evaluation. Tenax TA gave the best separation between cases and controls with a Q(2) = 0.434 and R(2)Y = 0.873 for three components. Analyses of samples taken with Carbopack B and Chromosorb 106 showed no ability to discriminate between the two classes.
