Operation Principle

CarlThe reaction formula for physisorption with water is;

I2+SO2+3C5H5N+H2O―→2C5H5N•HI+C5H5N•SO3……⑴

C5H5N•SO3+CH3OH―→C5H5N•HSO4CH3………………⑵

In KarlIn the Fiske and Subbarow coulometric titration method, the sample is added to the reagent, and the iodine produced by electrolysis at the anode reacts with the water in the sample. According to Faraday's Law, there is a direct proportionality between the quantity of electricity and the amount of substance. As shown in the following equation:

2Iˉ―2e―I2………⑶

By (no Chinese content provided)1The ratio of the molar amount of iodine to that of water is equal. When the sample is injected into the reagent, the water in the sample participates in the reaction. The consumption of iodine during the reaction can be reflected by the instrument, and the calculated moisture content is directly displayed on the digital indicator.

   The instrument features an automatic control system for electrolytic current, which can automatically select the size of the electrolytic current based on the moisture content of the sample.400Millamp, during the electrolysis process, the water content gradually decreases, and the electrolysis current proportionally diminishes until the corresponding electrolysis endpoint control circuit is activated. This system ensures high precision, high sensitivity, and high speed throughout the analysis process. Additionally, during the testing process, there are inevitably some interference factors, such as moisture intrusion from the air, which causes the electrolysis cell to absorb moisture and generate a blank current. However, due to the instrument's automatic blank current deduction function, the numbers displayed on the digital indicator are the actual water content in the sample. When the water content is low, the electrolysis current used is small; when the water content is high, a larger electrolysis current is required. When the electrolysis current decreases to the stored electrolysis current value, the endpoint is reached, and the endpoint indicator lights up and the buzzer sounds to alert the analysis.
