In food, flavor and fragrance science, panelists smell or taste products and a scientist would like to directly measure what the panelist tastes with an quantitative, real-time method such as PTR-MS. For the direct introduction of nose-space air to the PTR-MS, IONICON has developed the N.A.S.E. for real-time analysis of nose-space air.
Optimized sample gas transfer
Many compounds of interest in aroma analysis, e.g. Vanillin, are very "sticky" and can condense on the inner surfaces, especially cold-spots, of a sample transfer system. For a fast and reliable transfer of trace aroma compounds, the sample transfer system of the N.A.S.E. is made of highly inert materials in combination with a sophisticated heating system and an efficient sample flow paths. The N.A.S.E. can be used with all real-time trace gas analyzers and is optimized for IONICON PTR-MS systems.
