1. cTongue introduction: 

The cTongue electronic tongue mainly uses inert metal electrodes to form a stable sensor array. The original combined pulse relaxation spectrum idea is excited by voltammetric electrochemical pulse technology, and the overall information of the measurement object is obtained through interactive induction analysis technology, using big data perform a comprehensive analysis of the sample.

2. cTongue Principle: 

The cTongue electronic tongue can simulate the human taste perception mechanism, using a series of "cross-sensitive" electrochemical sensor arrays composed of electrode pairs to perform in-depth liquid analysis on "various compounds" to detect sample information, and can be passed through a dedicated application Combined with a variety of pattern recognition algorithms to quickly view the results of a given analysis, the overall quality of the tested sample is analyzed.

Different from the chemical method, the output of the sensor is not the analysis result of the sample composition, but a signal pattern related to certain characteristics of the sample. These signals can be obtained through the pattern recognition analysis of the computer.

3.cTongue Application 

 cTongue electronic tongue has long-term experiments and application research in the identification of true and false liquid foods such as alcohol, beverage and tea, product quality control and shelf life of brand enterprises, rapid detection of agricultural residues, rapid detection of pathogenic microorganisms, etc. it has shown obvious technical advantages and accumulated many mature application examples. As a new testing technology, it not only provides relevant research departments and testing departments as conventional scientific research instruments, but also provides intelligent quality monitoring means for on-site real-time and rapid testing for large-scale products.

Ctongue electronic tongue is mainly used for:

Acid, sweet, bitter, salty, fresh, five taste determination

Product quality stability and identification of true and false

Qualitative and semi quantitative determination of some trace specific components

Rapid qualitative and quantitative detection of pathogenic microorganisms
