I know about diluted testing and the hows and whys of it. they make prefect sense and it works. But after replying to another thread about .25 ppm of ammonia no mater what a person did every day for 3 weeks, I got to wondering. especially since the thread in question had another poster comment about how hard it would be even to tell the difference between .05, .10, .15, ,20 and .25.
Well this got me to wondering. Would the reverse work as well to help delineate say between .125 and .25 ppm of ammonia if we did a concentrated test? Suppose one only filled the test vial with 1/2 the amount of tank water of alternatively added twice the number of drops of the reagent(s)? Could one then not divide the results by 2 and get the real level? If the concentrated test read .50, this would mean it was really .25. But if it read .25, we would know it was really .125.
In theory this makes sense, but who can tell me if it will work in practice. That much extra reagent may make things not work right for reasons of which I am not aware. Might the error potential may be so much greater that the results would be too inaccurate w/o using more sophisticated mixing and dispensing equipment?
if you have a background or knowledge that can help with an answer to this, please post it.
