适用范围
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 > 0,05 mg/I for bromide and for nitrite, and > 0,1 mg/I 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. ≥ 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.
