Characterization refers to identification of volatile chemicals that originated from a sample (packaging, beverage, food, etc.) and, when useful, measurement of corresponding aroma activity of the volatile chemicals. To quickly screen chemicals for their aroma activity, we utilize gas chromatography-mass spectrometry/ olfactometry (GC-MS/O). When measuring aroma activity, key aroma impact compounds are identified. This data is particularly important in QA and product development. We utilize a time intensity GC-MS/O method that also employs voice recognition software. Aroma intensity (on a 1-4 point scale with 1 = faint and 4 = strong) is plotted vs. time of perception, along with the aroma descriptor. Coupled with chemical identification obtained from gas chromatography-mass spectrometry, this presents a powerful tool.

Volatile Analysis scientists are experts with sensory assessment, sample preparation, and instrumental analysis including GC-MS and GC-MS/O.
