Calibration gas generation system

The Permeater is a gas generator for calibration purposes that utilises permeation and diffusion tubes to generate the calibration gas. When the permeation and diffusion tubes are set at a constant temperature, the weight of both the permeating and the evaporating diffusion gas will be respectively set at constant levels. In this manner, calibration gas is continuously generated by setting both tubes at a constant temperature and providing a constant flow of dilution gas such as air or nitrogen. This method is highly reliable because gas concentration levels are determined based on the dynamic weight loss obtained from measurements such as rate of permeation diffusion or evaporation diffusion as well as the quantity of dilution gas calculated by weight.
