The Martek Mark 24 Cation Conductivity System provides accurate, on-line determination of specific and cation conductivity values  as well as calculated pH measurements in ultrapure water processes. Calibrated to ASTM and NIST standards, the Martek Mark 24 Cation Conductivity System displays data in direct engineering units on a large colorful display while offering both digital and analog output signals for external recorders and other data acquisition equipment. 

While specific conductivity provides measurement of total impurities, cation conductivity further refines the conductivity measurement to yield invaluable data. Utilizing a strong acid hydrogen cation exchange resin column, cationic species and amines such as ammonia and sodium are removed while mineral salts such as chloride and sulfate are converted into more conductive acids. Utilizing a well-proven algorithm, a pH measurement can also be determined from specific and cation conductivity values for systems utilizing ammoniated chemistry.

A cooled condensate sample stream is fed to the Martek Mark 24 Cation Conductivity System. The sample flow is controlled by a flow meter and directed to a conductivity sensor that measures the specific conductivity of the inlet stream. Next, the sample passes through a cation exchange column then is fed through a second conductivity sensor that measures the cation conductivity before exiting to drain. In addition, the specific and cation conductivity measurements can be used to provide a calculated pH measurement eliminating the need for additional, costly instrumentation.
