What is an electronic nose instrument? What is its function?

The electronic nose instrument is also called an olfactory fingerprint analyzer or an odor fingerprint analyzer. As an odor analysis device, the emergence of the electronic nose has been widely used in production and life, and has become a powerful assistant for odor detection and analysis. So what exactly is this instrument? What kind of function does it have?

What is an electronic nose

The detection objects of the electronic nose are mainly volatile flare substances. When one or more aroma substances pass through the electronic nose, the "odor fingerprint" of the taste substances can be sensed by the sensor and extracted by a special intelligent pattern recognition algorithm. Different gas samples can be identified by using different "odor fingerprint" information of different kinds.

In addition, some specific flare materials can characterize the comprehensive quality information of samples under the influence of multivariable factors, such as different raw material production areas, different harvest times, different processing conditions and different storage environments.

The role of the electronic nose instrument

Engineering management: amount of additives in food manufacturing, control of industrial cleaning process, control of fermentation process, amount of artificial gas in natural gas, manufacturing management of packaging in food industry, and process management of frying or grilling.

Quality control: Odor of oil, freshness of food, scattered gas in packaging, solvent residue of polymer, deterioration of flavor, characteristics of pharmaceutical gas, aroma of resin, beverage, etc.

Environmental safety management: foul odor in wastewater purification process, fertilizer odor, filtration process management, organic solvents in studio air, bacterial identification, leakage control, combustion management.
