  Full Description ADOPTED_FROM:EN ISO 23913:2009 This International Standard specifies FIA and CFA methods for the determination of chromium(VI) in various types of water. The method applies to the following mass concentration ranges: FIA: 20 µg/l to 200 µg/l and 200 µg/l to 2 000 µg/l for surface water, leachates and waste water. CFA: 2 µg/l to 20 µg/l and 20 µg/l to 200 µg/l for drinking water, ground water, surface water, leachates and waste water The range of application may be changed by varying the operating conditions. Sea water may be analysed by these methods with changes in sensitivity and after adaptation of the reagent and calibration solutions to the salinity of the samples.
