| Abstract: | One of the outstanding properties of PTR-fMlS is that it allows for a direct and absolute quantification of volatile organic compounds in the gas-phase. Here we examine this on a model sample of known concentration. The head space of an ethylbutyrate solution is stripped for 14 hours with a flow of 500 sccm/min, until the solution is completely depleted from ethylbutyrate. The measured PTR-MS count-rate is transformed into g/min of released ethylbutyrate. The cumulated amount turns out to be within a few percent of the initial 1000 microgram present in the solution. We then apply the method to in-mouth aroma release of ethylbutyrate to quantity breath-by-breath the quantity exhaled through the nose. Currently several experimental parameters that are not fully taken into consideration may affect a direct quantification (e.g transmission function of MS, humidity of sample gas). Work is underway to resolve these issues. |
