Sherwood Scientific™ Chloride Standard Solution, 200mg/L

The measurement of salt (Sodium Chloride) concentration in the Food and Dairy Industry is universal. Salt and salinity also represents serious contamination in industrial processes. The sensitivity of the coulometric method enables measurement in the ppm range in boiler feed water, polymer washes, bore hole slurries, as well as soils analysis and others.

The Model 926 method is based on a coulometric titration and is an absolute method where the reagent, the silver ions, is precisely and quantitatively generated at the time of the analysis by passing a constant current between donor electrodes. The end point is detected by the use of sensing electrodes which measure the change in solution conductivity which occurs when excess silver ions are present in solution.
