DIN EN ISO 19340:2019

Water quality - Determination of dissolved perchlorate - Method using ion chromatography (IC) (ISO 19340:2017); German version EN ISO 19340:2017

This International Standard 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 greater or equal to 1 micrograms per litre.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.
