Moisture content is one of the important indicators of material quality, which is of great significance for production and quality control in fields such as chemistry, medicine, and food. The volumetric water titrator, as an accurate instrument for determining the moisture content of substances, has received widespread attention for its high precision, high sensitivity, and wide applicability.Volumetric water titratorIt is achieved by accurately titrating Karl Fischer reagent into a sealed titration cell added to the tested sample through an accurate measurement system. The total amount of Karl Fischer reagent consumed at the endpoint is calculated to determine the total amount of water reacted in the sample, and then the water content in the sample is obtained.

　　Volumetric water titratorUsage steps:

1. Preparation work:

Check the airtightness of the instrument to ensure that the titration cell and electrode connections are correct.

Prepare Karl Fischer reagent.

2. Instrument calibration:

Use pure water or standard solution (such as 0.1 mg/g water) for titration calibration, repeat at least 3 times, and take the average value.

3. Sample determination:

Liquid sample: directly injected into the titration cell; Solid sample: Weigh and add through a solid sampler.

Start titration, the instrument automatically records the endpoint volume and calculates the result.

4. Data processing and cleaning:

Export measurement data for statistical analysis.

Clean the titration cell and electrodes with anhydrous methanol to avoid residue interference in the next experiment.

When using this device, safety operating procedures should be strictly followed, and attention should be paid to preventing hazards such as electrolyte splashing and electric shock. Regularly maintain and upkeep the instrument, such as replacing the electrolyte, cleaning the titration cell, etc., to ensure the normal operation of the instrument and the accuracy of the measurement results.
