Abstract
A method of determining the relative component proportions of at least one each of: a buffer; an acid or a base; a solvent; and optionally a salt, for providing a liquid mixture of pre-defined pH and ionic strength, wherein the relative component proportions are determined using the equation of Debye-Hückel, wherein the ion size parameter a in the Debye-Hückel equation is determined as the weighted mean ion size of all species contributing to the ionic strength of the liquid mixture, and wherein the ionic strength of each species is used as weighting parameter. The present method is also applicable in a method of providing a liquid mixture. Further there is provided a buffer preparation device.
