Abstract

A method for determining the content quantities, solubilities and/or saturation pressures of gases dissolved in a liquid, which is characterized in that in order selectively to determine the individual content quantities of at least two gases dissolved in a liquid sample, more particularly carbon dioxide, nitrogen and/or oxygen, and/or the solubilities or saturation pressures thereof, the volume of at least one measuring chamber filled with the liquid for testing is increased the volume of at least two steps by volume increase factors differing one from another, each having numerical values greater than 1, in that, after each of the volume increase steps, the equilibrium pressure established in the measuring chamber is ascertained, and in that, on the basis of the at least two measured pressure values obtained in this way, the content quantities of the individual gases dissolved in the liquid, and/or the solubility or saturation pressure thereof, are calculated individually. Also disclosed are several variants of a device for implementing the analysis method.
