ICP results and questions.

[USMA36]

The first result shown is not 0 ppm tds. It is VERY high. More than a thousand ppm tds.

How do you figure? Unless like I said earlier salt water somehow got in my rodi container and contaminated it. I have 2 tds meters both show zero and between 30 and 40 tds before going through the rodi system.

Ppm tds is essentially (oversimplifying a bit) the concentration of ions in ppm, or mg/l. You have over 1,600 ppm tds from sodium and chloride alone. Also, 1 psu salinity is more than a thousand ppm tds.

so either it was contaminated somehow, or the company made a mixup.

Thanks. I'll have to send them another sample.
