In this study, the sampling rates of TCA and TCP for Tenax TATM-based radial passive samplers have been calculated in indoor ambient with high humidity. A TD–GC–MS/MS method was suc- cessfully applied for the calculation of the sampling rates and for the analysis and quantitation of the passive sampling cartridges. As far as we know, this is the first method for the analysis of TCA and TCP in indoor air using passive sampling. The proposed method effi- ciently allows trapping and quantitative desorption of the analytes. The suitability of three types of cartridges with different sorbent combinations was tested and Tenax TATM sorbent was found to be the most appropriate for sampling of the target compounds. The applicability of the technique in real samples was tested in differ- ent places in two wineries. The method showed enough sensitivity to detect the two compounds within short periods of sampling at ng m−3 levels that are below their respective odour thresholds. The calculated sampling rates can be used for the monitoring and quan- tification of TCA and TCP in wineries’ ambient air using passive sampling.
