Item Application of bubble columns to gas-liquid chromatography(1965) Owen, George Rice; Deans, H. A. (Harry A.)When a gas bubble rises through a liquid in a tube of suitable internal diameter, the thin liquid film flowing past the bubble approaches equilibrium with the contents of the bubble. If perfect mixing within the bubble is assumed, all the gas contacts all the liquid in the column. This is the essential requirement for a quantitative chromatographic situation. This work is an evaluation of the practicability of such a bubble column as a chromatographic device. As a test of the system, the equilibrium K-value for ethane in n-decane at 75°F and infinite dilution was obtained experimentally and compared with literature values to evaluate the validity of the method. The results agreed very well with literature data, and it was concluded that further development of the technique is well justified.
