  • Method and device for detecting mercury
    Patent number: 6589795
    Abstract: The present invention relates to a method and a device for detecting mercury in a sample solution, the mercury being contained in the sample solution in cationic form and as an organic compound, by means of a detection device comprising an atomic spectroscope provided with a measuring cell which is suitable for detecting mercury gas, a noble-metal concentrator for concentrating the mercury and a control unit, the mercury being converted into the gas phase and being adapted to be concentrated by means of the noble-metal concentrator. The method according to the present invention is characterized in that the control unit controls the supply of the mercury gas to the measuring cell in such a way that, in addition to the measurement of the concentrated mercury, mercury gas of the same sample, which has not been subjected to the concentration step, is introduced in the measuring cell for the purpose of measurement.
