Embodiment Construction
[0042] Hereinafter, an odor evaluation device as an embodiment of the present invention will be described with reference to the drawings.
[0043]
[0044] figure 1 It is a schematic configuration diagram of the odor evaluation device according to the present example. The odor evaluation device of this embodiment is roughly divided into a gas chromatograph unit (GC unit) 1 , a mass spectrometry unit (MS unit) 2 , an odor measurement unit 3 , interface units 41 and 42 , and a gas recovery unit 5 .
[0045] The GC part 1 includes: a column 10 for separating the components contained in the gas to be analyzed, a column thermostat 11 in which the column 10 is installed, a sample injection part 12 provided at the entrance of the column 10, a sample injection part 12 provided at the column 10 The flow path switching unit 13 at the outlet of the outlet and the GC control unit 14 that controls these units.
[0046] The MS section 2 includes: a vacuum vessel 20; an ion source 21 that ...

The invention provides an odor evaluation device, an odor evaluation method, and an odor evaluation sample adjustment device. The present invention makes it possible to accurately measure the odor of a component contained in a gas to be analyzed. This odor evaluation device is provided with: a gas chromatograph having a separation column for separating, in the time direction, a plurality of components contained in a gas to be analyzed having an odor; a timing detection unit that detects the timing at which each of the plurality of components comes out of the separation column; a gas collection unit that collects, into a sample bag, a gas containing all or some of the components that come out from the separation column by introducing the gas to be analyzed into the separation column; a timing setting unit for setting the timing at which a component contained in the gas to be collected into the sample bag comes out of the separation column; and a gas introduction unit that introduces a dilution gas into a flow path that connects the separation column and the sample bag.
Description
technical field [0001] The present invention relates to an odor evaluation device, an odor evaluation method, and a sample adjustment device for odor evaluation. Background technique [0002] Fragrances added to foods, beverages, cosmetics, detergents, etc. are sometimes made by imitating the aroma (natural fragrance) of natural products such as flowers, herbs, and fruits. Most natural fragrances are complex fragrances made by mixing various ingredients, and various smells are formed according to the types of ingredients or the ratio of each ingredient contained. Furthermore, when there are many kinds of constituent components, an unexpected smell will be formed from the smell of each constituent component. In addition, not all components constituting the natural fragrance contribute to the formation of the smell, and the natural fragrance also includes components that contribute in a very small proportion or do not contribute at all. At the development site of a fragrance...
