A sensor based on the amalgam principle is described which is capable of detecting mercury quickly and easily even in ppb concentrations. The method is based on the formation of amalgam in an extremely thin (30 nm...60 nm) gold layer by contact (gaseous phase) with mercury-burdened ambient air. The silicon micromechanics is new; it enables the construction of miniaturized measuring systems integrating many important sensor components. The sensor itself consists of four meander-shaped gold resistance strips forming a measuring bridge. The formation of amalgam causes a change in the electric resistance of the gold layer which in turn changes the bridge voltage that is measured by a pre-amplifier. The sensor can be regenerated as mercury atoms...
