Abstract

1,213,459. Electro-chemical analysis. JOSEPH LUCAS (INDUSTRIES) Ltd. Feb. 13, 1968 [March 21, 1967], No.13201/67. Heading G1N. In an artificial kidney machine the concentration of the dialysate fed to the dialyser 11 is monitored in a conductivity cell 13 and compared in an A.C. bridge-circuit with the conductivity of a reference cell 16 to give a warning or effect a control if the concentration departs from a safe level.
