1、 Introduction to cNose Electronic Nose:
The detection target of cNose electronic nose is mainly volatile flavor compounds. When one or more flavor substances pass through the electronic nose, the "odor fingerprint" of the flavor substance can be sensed by sensors and extracted through special intelligent pattern recognition algorithms. By utilizing the distinct "odor fingerprint" information of different flavor compounds, different gas samples can be distinguished and identified. In addition, certain specific flavor compounds can precisely characterize the comprehensive quality information of samples under the influence of multiple variables such as different raw material origins, different harvest times, different processing conditions, and different storage environments. The electronic nose is composed of advanced sensors and is currently the most stable and accurate electronic nose among similar instruments. Very suitable for detecting liquid and solid samples containing volatile substances.
