Odor and Aroma Consulting

We utilize the most advanced scientific techniques and instruments currently available to detect and measure volatile chemicals responsible for odor.  We utilize gas chromatography-mass spectrometry/ olfactometry  to quickly determine what retention index values from a chromatogram correspond with odor.  This capability dramatically improves our capability to identify trace level chemicals responsible for off-odors.

Trichloroanisole, trichlorphenol, tribromoanisole, tribromophenol – We have considerable experience with detection and measurement of these problematic odors and precursor molecules.

To ensure new products exhibit desired aroma character and intensity, we employ spot-on sensory assessment, extraction methods and analytical analysis. Sensory includes quantitative descriptive analysis to ensure the attributes measured match those desired. Extraction methods depend on the nature of the material. Dynamic headspace extraction works for many products however specialized techniques such as sir bar sorptive extraction and solid phase micro-extraction also have a place. Analytical may employ GC-MS, GC-MS-MS,  GC-MS/O, or other method appropriate to answer a specific question.

Strategies depend on variables such as the type of material (liquid, solid, gas), location, quantity of material available, accuracy of odor descriptors, and suspected chemical class.  Some chemicals must be treated different due to unique characteristics, for example those contain sulfur sometimes require additional resources.

Based on answers to an initial questionnaire we will utilize the most appropriate and advanced scientific techniques and instruments currently available to detect and measure volatile chemicals responsible for odor. To find out more about our Odor Strategy Development service click HERE.

What method should be employed to answer your analytical questions?  If off-odor is a problem and the offensive chemical(s) is unknown, then GC-MS/O often provides the chemical identity in the most efficient manner.  If the identity of an off-odor is already known, then GC-MS may provide the necessary levels of precision and accuracy necessary.  More specificity is obtained when using GC-MS in selected ion monitoring. If the sample is very dirty or complex, then GC-MS_MS analysis may provide the best solution.   After careful study of the project goal, VAC will recommend which method provides the best opportunity for success.
