Ultratrace-level perchlorate in water containing 3000 mg/L of total dissolved solids (US EPA method 314.0) applying Inline Ultrafiltration

Main Document

Perchlorate is known as a potential contaminant in drinking water. Besides very few natural sources, it mainly originates from disinfectants, bleaching, propellants, etc. EPA method 314.0 requires to reach a method detection limit of 0.5 µg/L for perchlorate in reagent water. But also water with a very high content of total dissolved solids needs to be analysed by this method. Making use of the Metrosep A Supp 5 - 250/4.0 column fulfills all requirements of this method.
