Aroma and its perception can influence buying decisions. It is therefore indispensable for the industry to understand what we smell and taste when e.g. drinking a cup of coffee or enjoying a piece of chocolate, at the very moment the flavor molecules hit our receptors.
Flavor and taste of food can also vary over time, depending on raw materials or production processes etc. For a consistent brand image however, the aroma quality of food should remain stable.
Coping with requirements such as very high time resolution, basically real-

Advantages of high-
In food and flavor science researchers are often confronted with highly complex matrices. Thus, in order to separate compounds of interest from other compounds which share the same nominal m/z but have a different chemical composition (isobars), very high mass resolution is of utmost importance.
By introducing trichlorobenzene from a certified gas standard we determined the Full Width at Half Maximum (FWHM) mass resolution of an IONICON PTR-
However, by looking at the mass spectrum around m/z 153 in Fig. 2 one can see that there are in fact four ions which share this nominal mass (black line). For a low resolution instrument all four ions would be merged into one broad mass spectral peak and only the intensity of the sum of them could be measured. The high mass resolution of the PTR-
High sensitivity is particularly important when compounds of extremely low abundance have to be quantified with high time resolution. Utilizing the high sensitivity PTR-
