Standard Test Method for On-Line Determination of Sodium in Water

Importancia y uso:

4.1 Sodium is a pervasive contaminant and it is the first cation to break through deionization equipment. This test method allows measuring sodium in low-sodium waters at micrograms per litre (parts per billion) concentrations to identify contamination or to monitor equipment performance. Applications include monitoring makeup systems, condensers, condensate polishers, feedwater, boilerwater, and steam.

4.2 This test method is more sensitive and selective than conductivity measurements on high purity samples.
