M-100 Biosensor Analyzer Principle
This device is available for detecting the concentration of the sample by use of the specially designed bio-oxidase membrane electrochemical sensor.
M-100 Biosensor analyzer could automatically collect samples and put them into the test area. The test substance contained in the sample will undergo an enzymatic hydrolysis reaction under the catalysis of an immobilized bio-oxidase to generate hydrogen peroxide. The concentration of the test substance is calculated by the hydrogen peroxide concentration that is generated in the testing process of hydrogen peroxide electrode.
The device will automatically calibrate a standard solution with a known concentration, and the voltage of the standard solution is a measure of the concentration of the test substance. The unknown concentration can be obtained through the comparison with the voltage signal of the standard solution. And the electrodes of M-100 biosensor analyzer will be automatically cleaned by the buffer after each measurement is completed, then the next test can be performed.
