Cleaning, drying and assembly of titration cells for micro moisture analyzers

For the widely used trace moisture analyzer, I believe everyone has understood the previous introduction. It is composed of many parts. The following is the cleaning, drying and assembly of the titration tank of the trace moisture analyzer.

1. Before using the trace moisture analyzer, open all the glass ports of the titration cell. The titration cell, drying tube, sealing plug, and stirring bar can be cleaned with water, methanol or acetone, and the cathode chamber and measuring battery can be cleaned with methanol or acetone. But do not clean into the electrode leads. (Note that the cathode chamber and the measuring electrode must not be cleaned with water, otherwise it will cause measurement errors.) After cleaning, dry them in an oven at about 60C for 4 hours, and then let them cool naturally. (New electrolytic cells and electrodes generally do not need to be cleaned and can be used directly)

2. Put the color-changing silica gel into the drying tube (be careful not to put the powder into it); put the silicone rubber pad into the sampling cock, and screw it into the fastening stud; carefully put the stirring bar into the titration tank of the trace moisture analyzer; Then apply a thin layer of vacuum grease evenly on the grinding ports of the cathode chamber, measuring cell, drying tube, sampling cock, and sealing plug. To the corresponding part, turn it gently a few times to make it better sealed.

3. Use a dried funnel to inject about 100-120mL of electrolyte into the cathode chamber through the sealed port, and then use the funnel to inject the electrolyte through the dry tube socket of the cathode chamber. The liquid levels in the cathode and anode chambers should be basically level. After the completion, install the drying tube and sealing plug, and turn it gently a few times to make it better sealed (the electrolyte should be loaded in a fume hood).

4. Put the titration cell on the electrolytic cell seat of the trace moisture analyzer, and then insert the measuring electrode plug and the electrolytic electrode plug on the cathode chamber into the measurement and electrolysis sockets respectively.

The above points are the relevant introduction to the titration tank, one of the components of the trace moisture analyzer. The editor introduces to you the places that need to be paid more attention to in daily use. The titration tank is a place for holding items. It Whether it is clean or not is also directly related to the measurement effect, so you can operate according to the above introduction when cleaning it and other work.
