I tried searching for this answer but couldn't find anything. When doing the FAS-DPD test with the TF-100, I've seen the official (and extended) instructions say to add the reagent R-0871 until the sample turns clear. I've seen for the other tests that it's recommended to add until there is no color change. I've seen some people say they do that as well for the FAS-DPD test, which I started doing. I was wondering though if this will affect the results of the CC test since after adding R-0003, you add the same reagent (R-0871) as the FC test. In other words, if it turns clear, and I add another drop to make sure there's no further color change, I've added an addition drop of R-0871 to the mixture than if I had just stopped when I thought it was clear. Will this additional drop affect the CC reading?
