Free and combined chlorine - understand the difference

Testing the water for both free and combined chlorine allows you to know whether the water you've chlorinated is of sufficient quality to drink or disinfect your process, depending upon your application.


Water Testing in Renal Dialysis

Chloramine testing of water used for haemodialysis is mandatory as prescribed in ISO 13959:2014. The standard refers to testing for total chlorine, however understanding the difference between free chlorine and combined chlorine can help when making the decision as to which test method to use.
