Application scope:
According to the principle of microcoulometry titration, chloride ions in crude oil samples are immersed in water, and this water sample containing chloride ions is directly
added to the titration cell. Through electrolysis, silver ions react with chloride ions, and after the reaction is completed, electrolysis automatically stops to produce silver ions.
The microcomputer can automatically calculate the chloride ion or salt content in the sample based on the electricity consumption of the generated silver ions.
Main features of the instrument:
1. Any method that can titrate chloride ions with silver nitrate can use this instrument, which can more accurately determine, has high sensitivity, and is also simple to
determine, without the need to calibrate the solution. It is suitable for the determination of both high content chloride ions and extremely trace amounts of chloride ions in
samples. Computer control, display of the entire process status, parameters, and printing of various results.
2. The titration cell used replaces the ion membrane with a sand core, avoiding incorrect results caused by ion membrane damage.
3. Micro computer control, simple operation, reliable performance, good stability, and easy installation.
