Sampling method for use in odor measurement
First Claim
1. A method for detecting at least one odor in a gas sample, said method comprising:
- passing a gas sample into a thermal conditioning chamber or unit so as to control the temperature of said gas sample;
dividing the temperature controlled gas sample into a plurality of portions, wherein said portions are equivalents in terms of quantity of gas and/or in terms of their constituents; and
contacting each of said portions together with a different gas sensor, wherein said sensors are isolated from one another, thereby substantially avoiding an interference caused by an uncontrolled thermal convection.

Abstract
There are provided methods for detecting at least one odor in a gas sample. For example, such a method can comprise passing a gas sample into a thermal conditioning chamber or unit so as to control the temperature of the gas sample; dividing the gas sample into a plurality of portions and contacting each of the portions together with a different gas sensor. There is also provided an apparatus for detecting an odor that comprises a thermal conditioning unit adapted to control the temperature of a gas sample; a divider adapted to divide the gas sample into a plurality of gas portions; and a plurality of gas sensors disposed adjacently to the divider, each of the sensors being adapted to receive a portion of the gas sample in order to analyze it.

3. A method for detecting at least one odor in a gas sample, said method comprising:
-
controlling the temperature of a gas sample so as to obtain a desired temperature; dividing said gas sample having said desired temperature into a plurality of gas jets, wherein said gas jets are equivalents in terms of quantity of gas and/or in terms of their constituents; and contacting together said plurality of gas jets with a plurality of sensors for measuring and/or detecting odors. - View Dependent Claims (4, 5, 6, 7, 8, 9)

10. A method of sampling a gaseous composition in an odor measurement method, said method comprising controlling the temperature of said gaseous composition so as to obtain a desired temperature;
- dividing said gaseous composition having said desired temperature into a plurality of samples having substantially the same volume and substantially the same constituents; and
measuring each of said samples with a different sensor adapted for measuring odors.
- dividing said gaseous composition having said desired temperature into a plurality of samples having substantially the same volume and substantially the same constituents; and

11. An apparatus for detecting an odor, said apparatus comprising
a thermal conditioning unit adapted to control the temperature of a gas sample; -
a divider adapted to divide said temperature controlled gas sample into a plurality of gas portions, said divider being in fluid flow communication with said thermal conditioning unit, and wherein said portions are equivalents in terms of quantity of gas and/or in terms of their constituents; and a plurality of gas sensors that are isolated from one another, said gas sensors being disposed adjacently to said divider and in fluid flow communication with said divider, each of said sensors being adapted to receive a portion of said temperature controlled gas sample in order to analyze it, thereby substantially avoiding an interference caused by an uncontrolled thermal convection. - View Dependent Claims (12, 13)
