Standard analytes for E-noses and E-tongues

Odor and taste compounds are suggested here as standard analytes for e-nose and e-tongue instruments to provide performance criteria regarding the capacity of these electronic sensing devices to mimic human chemosensory responses. Representative odor and taste standards for sensitivity, suprathreshold intensity, and quality are proposed. Ultimately, a formal set of analytical standards should be established by the electronic sensing community. Subsets of these formalized standards could then be adopted for specific applications.
