ABSTRACT:
An apparatus and method are provided for diluting a concentrated solution to be analyzed which includes a Y-coupling for combining a diluent and the concentrated solution to form a mixture. The mixture is then divided into first and second parts, such as by a pumping arrangement, with the second part of the mixture being proportional in quantity to the quantity of concentrated solution. The first part of the mixture is then supplied to an analytical device for analyzing the mixture. A chamber including a movable wall element is provided which divides the chamber into two subchambers. The first part of the mixture is supplied to the subchamber on one side of the movable wall element, which causes the movable wall element to force a proportional quantity of diluent out of the subchamber on the other side of the movable wall element. The dispensed diluent is then conveyed to mix with the concentrated solution.
