I figured this was a Deep End topic as I ran across this JSPSI Article and was wondering if there was any validity to it. The article is entitled - "Interference in Melamine-based Determination of Cyanuric Acid Concentration" by Doug Latta of Aqua Clear, so therefore a guy in the "Pool Biz".
The short summary is this - sometimes there are interferences with the formation of the melamine cyanurate particles that form the colloidal suspension in the CYA test. Specifically there is some hypothesis that combined chloramines produce particulates when they react with melamine and therefore can give a false high reading on the CYA test. One suggested method to correct for this is to add a drop of bleach to the test sample before adding the melamine reagent to effectively destroy any CCs present. Then proceed with the test.
I tried combing the Taylor website for info to see if they have additives in the R-0013 reagents to correct for this and I searched TFP but did not find anything.
Has this practice ever been discussed or tried here? I'm solely asking for curiosity sake and do not endorse doing this at all unless there's some real scientific basis for doing so.
Thanks in advance for any insights.
