Abstract
This invention relates to a method and system for establishing and maintaining a precise concentration of dissolved gas in a liquid. More particularly, the invention relates to a method and system of establishing and maintaining a precise concentration of dissolved gas in a liquid by utilizing a gas blend comprising a sufficient concentration of the desired gas so as to be in equilibrium with the desired concentration of the gas to be dissolved in the liquid, i.e., a 'matched gas blend', to prepare a liquid admixture comprising the desired concentration of the gas. In this manner, the method and system of the present invention are able to produce liquid admixtures comprising precise concentrations of dissolved gas suitable for use in applications with tight specifications, and further, are capable of delivering the liquid admixture so produced to a point of use with substantially no loss of dissolved gas.
