Abstract:
A method of detecting mercury in a sample solution containing the mercury in inorganic form and as an organic compounds by means of a detection device comprisingan atomic spectroscope provided with a measuring cell adapted to detect mercury gas, a noble-metal concentrator for concentrating the mercury, and a control unit, the method comprising:converting the inorganic and organic mercury into the gas phase by reduction, thereby creating resultant gaseous mercury; supplying a first volume of the resultant gaseous mercury to the nobel-metal concentrator; concentrating the first volume of resultant gaseous mercury, thereby creating concentrated gaseous mercury supplying the concentrated gaseous mercury to the measuring cell; subjecting the concentrated gaseous mercury to a measurement; supplying a second volume of the resultant gaseous mercury to the measuring cell for performing a measurement; wherein the control unit controls the supply of the concentrated gaseous mercury and the second volume of the resultant gaseous mercury.
