Olfactometry is a method of determination of odorants concentration by presentation of odorants to humans and registration of the resulting sensations; the human sense of smell being used as a detector. This method allow determination of the human smell power for known odorant concentrations and also the determination of unknown odorant concentrations by mean of human smell sense. Guidelines are given for the determination of odour threshold and the derived quantity of odorant concentration. The anatomical\/physiological and psycho-physiological fundamentals of the odour phenomenon are presented. The terms used in olfactometry and their definitions are given. The measuring procedures are explained in a general matter covering the instruments, the sampling, the presentation of concentrations, the questioning technique, the panel, and the boundary conditions. The equations for the calculation of odorant concentration are given.<\/p>\n
This publication gives a very good definition of the olfactometry and the procedures to realize odour threshold determination. However, the information presented is general and has to be considered as guidelines, not enough details are given to realize standard tests.<\/p>\n","protected":false},"excerpt":{"rendered":"
