With PTR-MS, particularly if the NASE add-on for real-time nosespace analysis is being utilized, flavor release can be monitored and quantified with an extremely high time resolution.
Performing measurements even with a large amount of test subjects could not be simpler: The person uses the chewing gum and exhales into the NASE add-on, which is connected to an IONICON PTR-MS instrument. Pre-selected compounds are quantified and displayed in real-time on the instrument computer. However, one of the ample advantages of TOF based PTR-MS is, that not only the pre-selected compound data but the full mass spectra are saved in the measurement file. That is, no measurement data are lost and costly repetitions of large studies are effectively avoided.
