Abstract
Mass spectrometry is a well-known technology to detect O2 and CO2 in the off-gas of cell culture fermentations. In contrast to classical spectrometers, the proton transfer reaction mass spectrometer (PTR-MS) applies a very soft ionization strategy and therefore the spectra show less fragments and are easier to interpret. In our study we applied the PTR-MS technology to monitor volatile organic compounds (VOC) in mammalian cell culture processes. Interesting masses were identified and correlations between PTR-MS data and off-line parameters will be presented.

Abstract
We analysed the exhaled breath of a cohort of 50 healthy women using Proton-Transfer-Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS). To ensure that end-tidal exhaled air was collected, we used a Breath Collecting Unit, which sampled breath gas only when the CO2 signal was high. Samples were stored in inert Silco cans and analysed subsequently by PTR-TOF-MS. Components are characterized by their sum formula and were extracted from the raw data by matching them with a list of candidate compounds. A description of the average composition of the investigated cohort is given. These data can be helpful to identify compounds in breath measurements with quadrupole PTRMS systems, where a separation of isobaric compounds is not possible.
