Appeal No. 96-0881 Application No. 07/795,908 determining the actual concentration of individual concentrate components to be mixed as a dialysate; determining the actual conductivity of a dialysate to be formed by the concentrate components and water; combining said concentrate components with said water to form said dialysate; sensing the conductivity of said dialysate and comparing said sensed conductivity of said dialysate with said determined actual conductivity of said dialysate; and contolling the proportions of said concentrate components and said water in accordance with said comparison to obtain said determined actual dialysate conductivity. 14. An apparatus for mixing dialysate in a hemodialysis machine, comprising: means for determining the actual concentration of individual concentrate components to be mixed in a dialysate; means for determining the actual conductivity of a dialysate to be formed by the concentrate components and water; means for combining said concentrate components with said water to form said dialysate; means for sensing the conductivity of said dialysate and means for comparing said sensed conductivity of said dialysate with said determined actual conductivity; and means for controlling the proportions of said concentrate components and said water in accordance with said comparison to obtain said determined dialysate conductivity.
