  • Scaling factor for an output of an electrochemical cell
    Patent number: 8239138
    Abstract: A scaling factor for scaling an output of a first electrochemical cell, is determined in order to compensate for the effect on the output caused by an variation in value of a property of a working electrode of the first cell from a reference value of that property. A measured value for the property is obtained from a portion of material formed so as to have substantially the same value of the property as does the working electrode and the measured value is processed to generate the scaling factor.

  • MULTI-IONOPHORE MEMBRANE ELECTRODE
    Publication number: 20100012493
    Abstract: A polymeric membrane for ion sensitive measurement comprising a polymer, a lipophilic salt and at least two ionophores selective for different chemical species. The membrane may be used in a pseudo reference for measurement of a plurality of ions.

  • HDL Cholesterol Sensor Using Selective Surfactant
    Publication number: 20090203054
    Abstract: A method for the determination of the amount of cholesterol in high density lipoproteins in a high density lipoprotein containing sample, said method comprising reacting the sample with a surfactant which selectively reacts with high density lipoproteins in the sample, said surfactant being selected from sucrose esters, and maltosides, and measuring the amount of cholesterol in the high density lipoproteins, for example using an electrochemical technique.

  • Cholesterol Sensor
    Publication number: 20090188812
    Abstract: A method for the determination of the amount of cholesterol in lipoproteins other than high density lipoproteins in a lipoprotein-containing sample, said method comprising (a) electrochemically determining the amount of cholesterol bound to high density lipoproteins in the sample, (b) electrochemically determining the total amount of cholesterol in the sample, and subtracting the result of (a) from the result of (b).

  • HDL Cholesterol Sensor Using Selective Surfactant
    Publication number: 20090130696
    Abstract: A method for the determination of the amount of cholesterol in high density lipoproteins in a high density lipoprotein containing sample, said method comprising reacting the sample with a surfactant which preferentially reacts with high density lipoproteins in the sample, said surfactant being selected from hydroxyethyl glucamide derivatives and N-acyl-N-methyl glucamine derivatives, and measuring the amount of cholesterol in the high density lipoproteins, for example using an electrochemical technique.

  • Amperometer sensor
    Publication number: 20040265940
    Abstract: An amperometric sensor suitable for determining the concentration of analyte in a sample, said sensor comprising an oxidase enzyme and a substituted 1,4-benzoquinone compound which, in oxidized form, functions as a mediator specific to reduced enzyme and which has a lower oxidation potential than unsubstituted 1,4-benzoquinone.
