The measurement of mercury from flue gases is not straigtforward because of the low concentrations and the high vapour pressure of the mercury. In this paper a test device is described for specially coated filters developed for mercury collection. In this first step, silvered quartz fiber filters were used for this task under laboratory conditions. The mercury collection efficiency of the Ag-coated filters was tested in a sampling system connected to a special mercury generator. The filters were analyzed using an ED-XRF spectrometer. An average mercury collection efficiency of 88% was obtained.
