BS EN ISO 10304-1:2009 Water quality. Determination of dissolved anions by liquid chromatography of ions. Determination of bromide, chloride, fluoride, nitrate, nitrite, phosphate and sulphate
BS EN ISO 10304-1 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 to which BS EN ISO 10304-1 applies 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 to which BS EN ISO 10304-1 applies 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.
