Mercury Calibration Gas Generator MC3000
MC 3000 Mercury Calibrator
The MC-3000 is used for generating a continuous stream of a mercury vapor-loaded gas stream in order to check or calibrate mercury contamination analyzers. It is also suitable for all those applications where a gas stream with a preset and constant mercury concentration is needed.

Easily switch between the NIST or standard mercury vapor equation
Principle of Operation for Mercury Calibrator
An exactly adjustable carrier gas stream (normally air) is loaded with mercury in the first step. In the 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, and the dilution ratio is continuously adjustable so that final concentrations within the specified range can be obtained.
Construction of Mercury Vapor Generator
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 the case. The quantity of mercury is sufficient for the whole lifetime of the calibrator.
Operation of MC 3000 Mercury Calibrator
Using the NIST Traceable Calibration Gas Generator MC3000 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 that comes together with the calibrator. After waiting for about 30 minutes for stabilization, the saturation temperature is read from the display, and the mercury contamination concentration is calculated from the table.
