Water quality -- Determination of mercury -- Method using atomic fluorescence spectrometry
Samples containing mercury at concentrations higher than the working range can be analysed following appropriate dilution of the sample. The method detection limit will be dependent on the selected operating conditions and calibration range. With high purity reagents, a method detection limit of less than 1 nanogram per litre is obtainable.The relative standard deviation is typically less than 5 % for concentrations greater than twenty times the method detection limit. The sensitivity of this method is dependent on the selected operating conditions.
