Do any companies sell a ICP for just the RODI water? I know many include it in the aquarium water test.

I do not know. Is there something you are worried about?

not particularly. I just got new source water with a very high incoming TDS. My unit is taking it to zero but I wanted to see if there was anything getting by that my TDS meter wasn’t picking up.
@Randy Holmes-Farley or do you not think it is a concern?

I do not think that there will be problematic levels of most things in 0 ppm TDS RO/DI water that started as drinkable water. The two most likely to escape would be silicate and ammonia, and neither is a big concern at low levels.

Ok, that’s good to know. Just to mention it’s not specifically drinking water. It’s from a well. Technically supposed to be good water, it’s post softener

As long as it was deemed drinkable, it is likely OK. Just want to exclude the possiblility of industrial waste water or some theoretical situation where most of the TDS is from, say, copper chloride.

that is highly unlikely. I’m in a rural area. But the TDS is high, like 700. I’m assuming iron, sulfer, hardness

If you are interested in RODI tests ATI's ICP includes this with their test. I can't really speak for others or those that specifically target RODI.
