BS EN ISO 19340:2017

This standard BS EN ISO 19340:2017 Water quality. Determination of dissolved perchlorate. Method using ion chromatography (IC) is classified in these ICS categories:

• 13.060.50 Examination of water for chemical substances
• 71.040.30 Chemical reagents

This document specifies a method for the determination of dissolved perchlorate in water (e.g. drinking water, mineral water, raw water, surface water, partially treated water or swimming pool water, waste water from drinking/swimming pool water treatment plants).

Appropriate pre-treatment of the sample (e.g. matrix elimination) allows a direct determination of perchlorate ≥ 1 µg/l.

The working range is restricted by the ion-exchange capacity of the separator column. Dilution of the sample to the working range can be necessary.
