“…The absorption of gas into a liquid jet, such as shown in Fig. 2, is widely used to determine diffusion coefficients for a number of reasons (15,22,29,50,52,76,85,91,94,102,121,136,144,145). Jets are simple in design, have freedom from ripples, have small end effects, are stable, and have such short contact time that surface active agents do not have time to adsorb on the surface.…”
