APARATURA BADAWCZA I DYDAKTYCZNA Urządzenie do wytwarzania gazowych mieszanin wzorcowych z wykorzystaniem procesu barbotażu oraz permeacji

Reference gas mixtures are classified to reference materials and are mainly used for quality monitoring and identification of impurities in atmospheric air. They can be also used for calibration of measuring devices. Nowadays, there is a need to develop a new techniques for the preparation of reference gas mixtures [1, 2]. In this paper the design and the operating principles of instrument based on the use of barbotage and permeation processes were presented.
