[Mair2011] Mair, V.., J.. Dunkl, A.. Hansel, and I.. Kohl, "Breath gas analysis by PTR-TOF-MS in a clinical setting", 5th International PTR-MS Conference on Proton Transfer Reaction Mass Spectrometry and Its Applications, pp. 231, 2011.
Typical clinical (breath analysis) studies take several months to years. Employing a Proton-Transfer-Reaction Time-of-Flight Mass Spectrometer (PTR-TOF-MS) as an analytical tool for breath analysis, a constant performance of the instrument is essential. Here we report on the longterm performance of a PTR-TOF-MS for the analysis of exhaled breath gas in the frame of a clinical study. Performance data are shown for a period of 7 months. We characterized the sampling procedure, sample storage, and measured sensitivity and detection limit for a set of VOCs with relevance in breath analysis. Over the period of 7 months, we were able to achieve a high mass accuracy and precision in the range of ppm.
