Automated forced-choice dynamic-dilution olfactometer and method of operating the same
Is Version Of
An automated forced-choice dynamic-dilution olfactometer has an odor evaluation module having two or more panelist stations, with a plurality of sniffing ports at each station. At least one signal element at each station is connected to a data control unit. Separate air lines are connected to one each of the sniffing ports at each station. One of the air lines has an odor introduction port. The method of detecting an odorous stream of air in an automated forced-choice dynamic-dilution olfactometer and method of operating the same olfactor system comprises the steps of providing an odor evaluation module having at least two panelist stations; providing a plurality of sniffing ports at each station; providing a data control unit and connecting the control unit to a signal element at each station, providing separate air lines to one each of the sniffing ports at each station so that individual panelists at each station can separately sniff the air in each line, introducing an odor into one of the air lines, having the panelists at each station sniff each sniffing port to determine which air line contains the odor, and having each panelist actuate the signal element to advise the data control system as to which air line contains the odor.
