The conductivity of the product is 150 uS/cm, which is ~3 orders of magnitude higher than conventional distilled water. Could you recommend some methods to purify (to lower the conductivity) the product in the chemical lab at the university?

"Purity: 10 atom 18O%" ¿para una muestra de agua significa que contiene un 10% de agua con 18O?
1 answer-
Yes, this means that 10 % of elemental oxygen is 18O. This is atomic percent as opposed to mass percent.
