适用范围：The method specified in this standard serves to determine arsenic in water in concentrations by mass rangingfrom 2 μg/I to 100 μg/I if a volume of 20 μI is injected. The limit of determination is often lower and shall bedetermined in each laboratory by calibration experiments. The method is also suitable for higherconcentrations if the sample is diluted or a smaller volume of the test solution is taken. Arsenic in sludge andsediments can be determined using suitable digestion methods (see DIN EN 13346).
