Trace moisture analyzer use matters needing attention

The instruction manual of the trace moisture meter gives a full and detailed introduction to the process of use, assembly, maintenance and procedures of the instrument. However, in order to allow the customer to use it more safely and for a long period of time, the following points need to be noted when using the instrument:

First, the replacement of electrolyte.

1. Prepare a clean filter paper, put the two drying tubes of the electrolysis cell on the paper, take out the electrolysis electrode, drain the electrolyte in the electrolysis electrode, and slowly pour the electrolyte in the electrolysis cell. Do not pour the stir bar).

2. Under normal circumstances, there is no need to clean the electrolytic cell. Indeed contamination can be cleaned but it must be dried.

3. Cleaning: The electrolytic cell bottle, drying tube, injection cock, and measuring electrode can be cleaned with other anhydrous solvents such as anhydrous methanol or water; the white plate at the bottom of the electrolysis electrode is a honeycomb ceramic plate, and it is difficult to release it after containing water. If you do not use water for cleaning, if you really need to wash with water, be sure to put it in an oven at about 50°C for 6 hours after washing, then let it cool naturally in the oven.

Note: The cleaning liquid must not be touched by the plugs, wires and rubber caps during cleaning.

4, the electrolyte balance point adjusted after use.

5. Failure of the electrolyte: Two of the following three conditions may fail.

(1) The electrolyte is used for more than one month;

(2) The instrument can reach the equilibrium point, but the electrolyte color becomes darker and cloudy (normal color is clear);

(3) After repeatedly repeatedly shaking the electrolysis cell several times, it is still difficult to reach the end point in the electrolysis process.

6. In use, due to hot flashes of the air, frequent sample preparation, insufflation of the silicone pad of the injection port, or insoluble solid samples, it is difficult to reach the end point and the electrolysis cell can be repeatedly shaken.

7. The electrolyte must be changed carefully. Do not inhale or touch the reagent by hand. If contact with the reagent, rinse thoroughly with water. Because the reagents are large in taste and contain toxic ingredients, the ventilation in the laboratory is good.

Second, the measurement of matters needing attention 1, the sample into the electrolytic cell, the liquid injector needle to be inserted into the reagent, the sample should not be in contact with the electrolytic cell wall and the electrode.

2. The best display of water content for each injection of this instrument is 10μg~3000μg. Too small, the injection error is large. If it is too large, the long-term electrolysis time will expire quickly. In order to obtain accurate measurement results, the sample injection volume should be appropriately controlled based on the sample's moisture content.
