The total dissolved solids (TDS) in such water can vary but TDS could be as low as 1 mg/L. The electrical conductivity is generally less than 2 mS/m and may even be lower (<0.1 mS/m).
Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
www.iitk.ac.inTotal dissolved solids must not exceed 0.1 wt %.(e.g. 0.1 g per 100 ml of solution). There must be no suspended solids ( if in doubt filter a portion with 0.2 micron cellulose nitrate syringe filter). Sulphuric acid is to be avoided because it forms polyatomic species and causes rapid damage to the Ni interface cones.
