The parameters that can be fully automatically detected include:
Glucose, sucrose, lactic acid, glutamine, glutamic acid, lysine, ethanol, methanol, glycerol, xylose, pH, NH4+, K+, Na+, Ca2+, Osm, etc
*Can be converted to English version, with optional dilution function and upgraded online sampling function.
The M-900 plus is very suitable for the development of cell culture processes.
The M-900 plus has high accuracy and good precision, and many users who have used it have given evaluations that the analysis results are reliable, cost-effective, and fast. The testing time for a single project only takes 20 seconds to complete. When selecting multiple biochemical and ion testing parameters, all parameters can be tested in 2 minutes to meet customer needs.
Principle

M-900 plus uses immobilized enzyme membrane hydrogen peroxide electrode and ion selective electrode to detect the concentration of the test sample. Fix the oxidase corresponding to the experimental substrate in the enzyme membrane and catalyze the substrate to produce hydrogen peroxide. Hydrogen peroxide is measured through a hydrogen peroxide electrode, and the instrument obtains the electrical signal measured by the hydrogen peroxide electrode. The concentration of the test substrate is calculated from the hydrogen peroxide concentration.
Ion Selective Electrode (ISE) is an electrochemical sensor that can convert changes in ion concentration in a solution into changes in the corresponding electrode and reference electrode potentials. The logarithm of ion concentration in the solution is linearly related to the electrode potential. "Ion selective electrode" refers to an electrode that is only sensitive to specific ions. For example, ammonium electrodes are only sensitive to ammonium ions in the solution and are not sensitive to potassium ions.
M-900 plus automatically collects samples and imports them into the testing area. The test substance contained in the sample generates an electrical signal on a specific electrode. The instrument calculates the concentration of the measured substance by collecting electrical signals from the electrodes. Before testing, the instrument is automatically calibrated with a known concentration standard, and the voltage value of the standard solution is a comparative measure of the concentration of the test substance. By comparing the voltage signal with the standard sample, the corresponding parameter concentration of the unknown sample is obtained. After each measurement is completed, the sensor electrodes will be automatically cleaned by the system buffer and flow cleaning solution. After cleaning, the next test can be conducted.
