Online methanol concentration detection technology

[0023] A kind of methanol concentration online detection technology that the present invention proposes, comprises the following steps:

[0024] S1, original sample pretreatment: Sampling is carried out through the sampling device, the original sample is obtained, the original sample is randomly divided into 3 parts, and they are respectively packed in volumetric flasks to obtain the sample to be tested;

[0025] S2, measurement of the sample to be tested: measure the mass and volume of the sample to be tested, calculate the density of the sample to be tested through the mass and volume, and input the density data of the sample to be tested into the computer and save it, take the standard methanol solution, and measure the quality of the standard methanol solution and volume, calculate the standard methanol solution density by mass and volume, and input the standard methanol solution density data into the computer and save;
