Odor and Emissions Research Services Lab Olfactometry can determine an odor's DT, Hedonic Tone, and Intensity using our trained Odor Assessors. We are always interested in odor and air-quality related research. Lab Olfactometry manufactures and pre-conditions Tedlar® bags on site to assure odor free sampling materials. The bags are pre-conditioned via heating in a drying oven at 100º C for 24 hours, then purged with Zero-air.
The Commercial Core Lab can analyze odor samples for a variety of sources. Each odor panel includes quality assurance analyses including a 40 ppm n-butanol standard and a machine blank. Tedlar® bags and/or a vacuum chamber can also be supplied. The Lab uses a Triangular Force Choice Method Olfactometer.
The Lab also has the ability to analyze ambient air samples collected on sorbent tubes with GC/MS and GC/MS-olfactometry. The GC/MS-O has the ability to couple Odor panelists data with analytical data collected from a GC/MS. Analysis for Thermal desorption tube samples can be arranged in advance and can be from a variety of sources.
