Abstract
An olfactometer has a sniffing port, a sample supply for generating a sample flow constituted by a carrier gas and sample head space from a saturation chamber and for supplying the sample flow to the sniffing port, a carrier gas supply, and mixer for predetermined dilution of the sample flow. The carrier gas supply includes mass flow controllers with variable flow rates disposed before the saturation chamber for providing variable carrier gas flow to the saturation chamber. A multiplicity of capillaries of different diameter connect the mixing means with the sniffing port via individual injectors. A computer may be interphased with the olfactometer to regulate the amount of sample and/or carrier gas in the sample flow.
