Evaluation of stability of volatile organic compounds in SUMMA canisters at different humidity levels

Popis výsledku v původním jazyce

Volatile organic compounds (VOC) occur in traces in atmosphere and even in trace levels, these compounds pose serious health hazard. Sample stability, recovery, effect of temperature and moisture management are a few critical points taken into consideration while sampling and analysis of polar and non polar VOCs. In the presnet work, stability study was carried out for polar and non polar VOCs in SUMMA stainless steel canister. Compounds recoveries were assended in dry and humid canisters. Canister samples were prepared with 0,25,50 and 100 % humidity. Moreover, the study with each humidity level was performed with two different concentrations (approx 50 &500 qgm3) of each compound to evaluate the influence of lower/higher concetration. Before startingexperiment, various parametres used for the measurement of VOCs from canister system were optimized and method detection limit was calculated as the accuracy of analytical measurement is the key part of stability study. Polar compounds l
