*Generates elemental mercury vapor *ca. 10 ... 500 µg/m³ Hg° *Compact sized and portable *No permeation principle - no need to calibrate the calibrator *Microprozessor controlled
Fields of applicationThe MC-3000 is used for generating a continuous stream of a mercury vapor loaded gas stream in order to check or calibrate mercury analyzers. It is also suitable for all those applications where a gas stream with a preset and constant mercury concentration is needed.
Principle of OperationAn exactly adjustable carrier gas stream (normally air) is loaded with mercury in a first step. In a second step the gas is supersaturated by cooling. Subsequently the excess mercury is condensed in a special cell to get exactly saturation. The gas is then diluted, the dilution ratio is continuously adjustable that final concentrations within the specified range can be obtained.
ConstructionThe flow regulators and displays are mounted onto the front panel and are easily accessable. For mobile use the aluminium case has two carrying handles. The mercury containers are mounted inside of the case. The quantity of mercury is sufficient for the whole life time of the calibrator. Operation Mercury Instruments MC-3000 in operation: calibration of a mercury analysis system. Using the MC-3000 is easy: The device is placed on a flat surface and connected to the carrier gas source, for example a compressed air line. A portable air pump with a tank is delivered as an accessory. The MC-3000 is then switched on and the desired mercury concentration is set via keypad. After allowing for 30 minutes for stabilizing the calibrator delivers a constant stream of air with the pre-set mercury concentration.
