ICP values off?

[Maximitsurugi]

These are readings from a flushed RODI unit with new filters. Why am i getting these values? I thought 0 TDS meant 0.

Im still trying ti get the hang of ICP but thats weird. Any ideas?

How accurate is your TDS meter?
ICP is prob not perfect either

Tested with both hand held and on unit. Strange right? Thanks Lapin

Any ideas @Randy Holmes-Farley

Maybe it leached or contaminated into the sample after the DI, or maybe it is just noise in testing.

My guess is the latter unless the method was optimized for pure water (rather than seawater). Especially the strontium is not real in 0 ppm TDs water made from drinking water.

I had similar results from my last RODI test as well. Normally zeros across the board. I assumed noise. Hand held hanna TDS checker reads 0.
