Abstract
The present invention relates to the preparation of liquid mixtures, and more particularly to the preparation of a liquid mixture, such as a buffer, wherein the conductivity of the liquid mixture is measured and the pH indirectly determined if the buffer concentration is known. Another object of the present invention is to provide a method of preparing a liquid mixture with a predetermined pH value by using conductivity as feedback control parameter.
