Mercury Calibration Gas Generator MC 3000

Generates Elemental Mercury Vapor

• Generates elemental mercury gas
• ca. 10 ... 500 µg/m³ Hg
• Compact sized and portable
• No permeation principle - no need to calibrate the calibrator
• Microprocessor controlled

Fields of application

The 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 Operation

An 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 exact saturation. The gas is then diluted, the dilution ratio is continuously adjustable
that final concentrations within the specified range can be obtained.

Construction

The flow regulators and displays are mounted onto the front panel and are easily accessible. For
mobile use the aluminum 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

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 dilution ratio is selected according to a table which comes together with the calibrator. After waiting for about 30 minutes for stabilizing the saturation temperature is read from the display and the concentration is calculated from the table.
