Abstract
A method for automatically determining the quantity of a soluble component in a powdery product is disclosed comprising providing a sample receiving container, weighing the sample receiving container, computing the weight of a predetermined quantity of solvent for the soluble component and introducing that predetermined quantity of solvent to the sample receiving container, introducing a predetermined quantity of the powdery product into the sample receiving container including the computed weight of solvent, weighing the solvent containing container with the predetermined quantity of powdery product and solvent therein, computing the weight of the predetermined quantity of powdery product, computing the weight ratio of the predetermined quantity of powdery product to the predetermined quantity of solvent, agitating the predetermined quantity of powdery product and solvent within the sample receiving container so as to create a solution thereof, determining an electrical characteristic of the solution, and correcting the electrical characteristic of the solution as a function of the weight ratio of the predetermined quantity of powdery product to the predetermined quantity of solve…
