In practice, the working range is oftenfrom 10 ng/I to 10 μg/l.Samples containing mercury at concentrations higher than the working range can be analysed followingappropriate dilution of the sample.The method detection limit (XDL) will be dependent on the selected operating conditions and calibration range.With high purity reagents, a xDL of less than 1 ng/I is obtainable.The relative standard deviation is typically less than 5 % for concentrations greater than twenty times themethod detection limit.The sensitivity of this method is dependent on the selected operating conditions.【中国标准分类号】: Z16【国际标准分类号】: 13_060_50【页数】: 21P.;A4【正文语种】: 英语
