RODI Results

[JGT]

Recently had a ICP test done on my RODI and a few things came back high. All are in ug/l.

Manganese 1.7
Silicon 58
Lanthanum 39.6
Sulfur 40.9
Sodium 104
Calcium 79.8
Magnesium 20.8

Anything for concern or what might be causing it?

looking at my last ICP, Manganese, silicon, and Lanthanum was 0.0. Sulfur, Sodium , Calcium, and magnesium are not on my list. So I would assume that those was not tested.

I would guess that you need to either change your RO cartridge and/or DI change.

Thanks, it’s weird cause my TDS is 0 though.

I don't think those are an issue. remember, TDS with hobby grade measurements is 0 or 1 ppm TDS, which means 0 or 1,000 ug/L total ions. Those do not account for 1,000.

I suspect the lanthanum is not accurate.

Thanks Randy. Unless I splashed some LC into my topoff tank when I was mixing up a batch. Quite possible.
