ATI ICP test. Send in RO or RODI water?

[Philipgonzales3]

One tube is marked RO water. Should I send in RO water before the DI or RODI water?

Send your RODI water

You will get RODI results like it says in #2

My RODI water is 0ppm. Doesn't that mean that it's pure water or is that not what this means? Can there still be metals or anything in the water at 0 TDS?

Silicates, for one, can be in 0 TDS water. It only measures things with a charge iirc. So there can be other stuff, worth doing since its included
Edit, TDS measures ionized particles

Ok cool. Good to know. Thanks!
