Calibration of gas mixers in the low flow range

Most dynamic gas mixers use flow regulators to create defined gas mixtures. QCAL Messtechnik uses thermal mass flow controllers ( MFC ) from various, renowned manufacturers. These MFCs are reliably calibrated proven by a calibration certificate – traceable to National Standards. But these calibrations are limited. The whitepaper describes 2 methods to extend the application range of gas mixers ...

What is a Gas Blending System?

Gas blending systems are used to create mixtures of different gases for specific uses. These mixtures, or blends, are typically specified by molar fraction as a percentage or as a parts-per unit. In ...

Generation of Mercury Calibration Gas

The MC-3000 generates a continuous stream of a mercury vapor loaded gas in order to check or calibrate mercury analyzers. An exactly adjustable carrier gas stream (normally air or nitrogen) 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, ...
