Frequently asked questions and answers for moisture detectors
The color of the anode electrolyte is not bright yellow, but between brown and dark yellow
If the color is too dark, it is a decrease in the electrode's responsiveness to the electrolyte. You can use a tissue to clean the double platinum needle electrode to remove adsorbed substances on the surface; Check if the measuring electrode is connected properly; The measuring electrode may malfunction.
Pre titrate fresh anode electrolyte, drift too high?
There is residual water in the titration system. The molecular sieve and silicone inside the drying tube can be replaced; Check whether the electrode interfaces and plug interfaces of the titration table are tight; Silicone grease can be applied appropriately to some loose interfaces.
What is the reason for the high drift during standby titration?
The water in the cathode pool seeps into the anode pool through the diaphragm. Can replace the anode pool electrolyte; Add a small amount of single component volumetric Karl Fischer reagent to the cathode electrolysis cell for drying; Maintain the liquid level of the anode solution higher than the liquid level in the cathode pool; Thoroughly clean the titration cup and remove the continuous side reactions caused by the residual sample from the previous experiment; Check the sealing of the titration system.
