The principle of inose
Using many metal oxide semiconductor sensor of different properties to make a sensor array, combined with specific intelligent learning and identification pattern recognition algorithms, intelligent bionic olfactory system is constructed. It is mainly composed of four components: (1) sampling means and the gas injection system (2) sensor array (3) sensor detection curve (4)intelligent pattern recognition software.
Inose gas sensor array (It requires a combination of application)
The definition of Inose:
Inose detection mainly target volatile flavor compounds.
When one or more than one kinds of flavor pass by the inose, "odor fingerprint" of the flavor compound can be perceived by special sensors and intelligent pattern recognition algorithm. Using different flavor of different "odor fingerprint" information, you can distinguish and recognize different gas samples. In addition, certain flavoring substances have multiple quality information affected by many variables, such as in different raw materials, different raw materials, different harvest time, different processing conditions and different storage environment. Inose is composed of the most advanced sensor, which are currently of the best stability, the highest detection accuracy of the electronic nose .
It is very suitable for detecting liquid and solid samples containing volatile substances.
