When a conductivity analyzer is used to monitor water quality in a power plant or other source of ultrapure water, the measurement can be distorted by the presence of treatment chemicals such as ammonia and amines. An easy way to eliminate the interference due to treatment chemicals is to pass the feedwater or condensate through a cation exchange column before conductivity is measured.

When the cation exchange cartridge removes the alkaline treatment chemicals which interfere, it conveys an additional benefit: metal cations are replaced by hydrogen ions. This increases the sensitivity of the conductivity reading. Hydrogen ions are the most mobile of all the positively charged cations. Because hydrogen ions have the greatest ability to conduct electricity, when hydrogen ions replace sodium, calcium and other cations, conductivity increases.

Waltron offers two types of brackets for mounting the cartridge: The Single Bracket Model 1111 and the Duplex Bracket Model 1112. Both are made of heavy duty stamped steel and are provided with pressure fitting(s), tubing, washer(s), lower receiving block(s), and a brass shut off valve. With the Duplex Bracket installed with two cartridges, if the first cartridge is depleted, the second cartridge continues to treat the sample. When the spent cartridge is replaced, the back?up cartridge is shifted to the upstream position. Thus the new cartridge always becomes the back-up.

Easy to follow installation instructions are included with each bracket.
