  • Ion selective electrode module for clinical diagnostics
    Patent number: 9297797
    Abstract: A method of determining an electrolyte in a sample including adding the sample to an electrolyte module, the electrolyte module including a dilution cup, a flow cell, and a pump, the flow cell having a flow channel with a first end and a second end, the first end fluidically coupled to the dilution cup, and the second end fluidically coupled to the pump; combining the sample with a diluent in the dilution cup to produce a diluted sample; operating the pump to aspirate the diluted sample into the flow cell; measuring the electrolyte in the diluted sample in the flow cell; and reversing the pump to dispense fluid through the second end to displace the diluted sample from the flow cell back into the dilution cup.
