• Suitability of five polymer sampling containers (Nalophan, transparent Tedlar, black layered Tedlar, Teflon and FlexFoil) for sampling and storage of six relevant to breath analysis volatile sulphur compounds: H 2S, MeSH, EtSH, COS, DMS and CS 2 was studied using solid phase microextraction (SPME) and gas chromatography coupled with mass spectrometry (GC–MS). Investigations were made with respect to the several factors like: recovery, background, influence of light, ageing effect and matrix effects. Additionally, the optimal reusability conditions were established. Findings suggest analyzing the breath VSCs within 6 h after sampling. Flexfoil bags were found to be the best choice for the VSCs storage up to 24 h (recovery about 90% with the exception of DMS). For shorter storing times (6–8 h) transparent Tedlar is a good alternative for Flexfoil (losses up to 10%).
