I can disclosure that I have done some "blind"test:
I have sent same water to Triton with different names so it would look like different sampels, and then compared the results;-) I have also sent same water to 2 different companies( ATI and Triton) and compared their results;_)
My conclusion from that "minitest"(of course not significant), is that their precision is good enough. The accuracy is maybe hinted by my other test, comparing between 2 different brands, and also there it was very good results with quite high accuracy, thus the results was very equal also in this group. The only totally wrong measure was the dKH by ATI. The measured wrong with 2.5dKH;_)...I wrote to them but never got an answer, so I will not use ATI anymore. I also noticed that concerning I and Si, there seems to be some cross reacting phenomena, and maybe Randy can comment this? These two elements had the biggest deviations (in same water).
Triton, and all ICP -providing company has some "problems": They offer analysis of several components(around 10 i think) where their level of detection is above the level of natural seawater. In these cases you cannot say so much of that analysis more than that do not have too much. despite that they have dosing recommendations sometimes. It is obvious that there is business in this also. So long as we understand that and learn us to interpret the results, I think these methods is a big step for the marine aquarist hobby.
