ISO 10304-1:2007 Water quality - Determination of dissolved anions by liquid chromatography of ions - Part 1: Determination of bromide, chloride, fluoride, nitrate, nitrite, phosphate and sulfate
This part of ISO 10304 specifies a method for the determination of dissolved bromide, chloride, fluoride,
nitrate, nitrite, orthophosphate and sulfate in water, e.g. drinking water, ground water, surface water, waste
water, leachates and marine water by liquid chromatography of ions.
The lower limit of application is W 0,05 mg/l for bromide and for nitrite, and W 0,1 mg/l for chloride, fluoride,
nitrate, orthophosphate, and sulfate. The lower limit of application depends on the matrix and the interferences
encountered.
The working range may be expanded to lower concentrations (e.g. W 0,01 mg/l) if an appropriate
pre-treatment of the sample (e.g. conditions for trace analyses, pre-concentration technique) is applied, and/or
if an ultraviolet (UV) detector (for bromide, nitrate and nitrite) is used.
