Description
technical field [0001] The invention relates to a solution concentration detection technology, in particular to a citric acid concentration analysis device based on a surface acoustic wave series resonator biological tongue, and a citric acid concentration analysis method based on a surface acoustic wave series resonator biological tongue. Background technique [0002] In the laboratory, it is often necessary to detect the concentration of the solution. When detecting the concentration of the solution, a special concentration analyzer is usually used for detection. However, the concentration analyzer is expensive, and it costs tens of thousands of yuan, which greatly increases the cost of the experiment. Therefore, it is necessary to design a concentration detection device with simple structure, quick operation and low cost, and a detection method of the detection device. Contents of the invention [0003] The present invention mainly solves the problem of high cost of usi...
