Summary

ISO 10304-1:2007 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 greater than or equal to 0,05 mg/ l for bromide and for nitrite, and greater than or equal to 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. greater than or equal to 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 UV detector (for bromide, nitrate and nitrite) is used.
