Abstract: There is provided a method of preparing a mixed liquid having a first property and a second property. The method includes providing a first set of liquids, a second set of liquids, and a third set of liquids. The method includes combining the provided sets of liquids. Further, the method includes varying at least one of the liquid flows of the first and second sets and at least one liquid flow of the third set to adjust the first property and the second property to their respective predetermined values in the resulting mixed liquid flow.

Abstract: A method of preparing a mixed liquid flow having predetermined characteristics, including a predetermined value of a first property and a predetermined value of a second property, comprising the steps of: a) providing a first set of at least one liquid flow each having a different first value of the first property; b) providing a second set of at least one liquid flow each having a different second value of the first property; c) providing a third set of at least one liquid flow of solvent; d) combining the provided liquid flows; and e) varying at least one of the liquid flows of the first and second sets and at least one liquid flow of the third set to adjust the first property and the second property to their respective predetermined values in the resulting mixed liquid flow.
