cation conductivity analyzer is often used to take out the CO2 from the reading. Degassed cation conductivity readings should be < 0.3 uS/cm or for a supercritical < 0.15 uS/cm. Overfeed of amine to the system will distort the true cation conductivity reading since it is the major source of CO2 in the steam.

Questioning The Relevance Of Cation Conductivity

In high-pressure boilers, these substances may generate decomposition products that may increase cation conductivity. When this happens, the higher cation conductivity fingerprint may add an undesirable masking effect to the monitoring effort. Of special concern is the potential presence of acidic anions such as Cl-that may go undetected. An
