1 Measuring Odor Intensity with E-Noses and Other Sensor Types

This paper addresses the problem of predicting human olfactory ratings from instrumental measurements. Specifically, the paper analyzes the ability of two commercially-available electronic nose instruments (the NST 3320 and the Cyranose ® 320) and three other sensing devices (a photoionization detector, a gold-film sulfur sensor, and an infrared laser detector) to match the performance of the human olfactory system in measuring odor intensity in a variety of realistic situations. These initial studies offer encouraging results for the two e-nose instruments, the PID, and the Au-film sensor
