When one or more than one kinds of flavor passby the inose, "odor fingerprint" of the flavor compound can beperceived by special sensors and intelligent pattern recognition algorithm. Usingdifferent flavor of different "odor fingerprint" information, you candistinguish and recognize different gas samples. In addition, certain flavoringsubstances have multiple quality information affected by many variables, suchas in different raw materials, different raw materials, different harvest time,different processing conditions and different storage environment. Inose iscomposed of the most advanced sensor, which are currently of the beststability, the highest detection accuracy of the electronic nose .
It is very suitable for detecting liquid andsolid samples containing volatile substances.
GasSensor Array
iNosetype electronic nose
The principle of inose
Usingmany metal oxide semiconductor sensor of different properties to make a sensorarray, combined with specific intelligent learning and identification patternrecognition algorithms, intelligent bionic olfactory system is constructed. Itis mainly composed of four components: (1) sampling means and the gas injectionsystem (2) sensor array (3) sensor detection curve (4)intelligent patternrecognition software.
Inosegas sensor array (It requires a combination of application)
Inose detection curves
S1 Ammonia, amines
S2 Hydrogen sulfide, sulfur
S3 Hydrogen
S4 Alcohol, organic solvents
S5 Volatile gases during food cooking
S6 Methane, biogas, hydrocarbons
S7 Flammable gas
S8 VOC (used for environmental air pollutiondetection)
S9 Oxy-hydroxide, gasoline, kerosene
S10 Alkanes, flammable gas
