Question
How often should the resin cartridge of the 9523 be exchanged?
Summary
9523 resin cartridge exchange frequency
Answer
The exchange frequency of the 9523 depends on the flow rate. The higher the flow, the earlier you have to exchange.  On average, the resin will be exhausted in about two months, but it may need to be replaced more often. 

There are two possibilities for checking when to replace the resin. 

One is to get a message from the analyzer, described in the 9523 user manual under the "Resin option".  You can program resin parameters to help the analyzer track how often you should replace the resin based on the parameters entered in the parameters section of the resin menu. 

The second option is a visual check.  There is a color change in the resin beginning in the inner center of the cartridge and going to the outer side.
