Hi
I was wondering if you could comment on a query I am having with my ICP test results.
I normally use a Hanna checker, the ultra low range phosphorus variety. I also use the standards that are available for this instrument, so I am reasonably sure I am getting a valid result from my checker.
That is until I looked at my recent ICP test. Accordingly I have a phosphate level of 0.28 mg/l where my Hanna checkers give me a range of between 0.05 to 0.02 mg/l an order of magnitude different.
I have a mixed reef tank with one fish. Would you have any idea why there would be such a large discrepancy before I take any remedial action please.
I am also aware of the accuracy/precision difference of the two instruments.
I would very much appreciate your thoughts.
Julian
