From the Representativeness of Sampled Odors to an Olfactive Camera.

Although representativeness is often a prerequisite when sampling odors, the methods used have never been assessed from the analytical and sensory perspective simultaneously. We validate several critical innovations in the methods used to sample odors, starting with a previously developed static-and-trapped headspace (S&T-HS) cell, to minimize sorptive biases and allow for thermodesorption of trapped odors. The addition of a desorption oven allows for restoration and testing of odors sampled by not only S&T-HS but also other techniques (solid-phase microextraction, headspace sorptive extraction, purge-and-trap headspace).
