  • Cation exchange capacity titration unit
    Patent number: 9011775
    Abstract: Disclosed herein is a cation exchange capacity titration unit comprising a titration cell having a closed bottom end in fluid communication with an open top end; a recirculation loop comprising a pump and a sensing unit, wherein the pump comprises a pump inlet in fluid communication with the bottom end of the titration cell, and a pump outlet in fluid communication with a sensing unit inlet, the sensing unit inlet being in fluid communication with a sensing unit outlet, wherein the sensing unit outlet is in fluid communication with the top end of the titration cell such that operation of the pump results in an analyte sample flowing from the bottom end through the pump, through the sensing unit, and back into the top end of the titration cell in a continuous loop. A method of determining the cation exchange capacity of a sample is also disclosed.
    Type: Grant
