Principle of the Cartesian Diver applied to Gasometric Technique

Abstract

IF for some reason or other the quantity of gas in a Cartesian diver decreases or increases, the the pressure to bring the driver to a standstill at a fixed level will change correspondingly, that is the pressure change will be a measure of the change in quantity of gas. If, therefore, within the diver processes take place involving liberation or absorption of gas, the rate of these processes may be estimated quantitatively by measuring at different times the pressures at which the diver is in (unstable) equilibrium at a fixed level.
