    IPC: G01N27/333

    CPC classification number: G01N27/333

    Abstract: The present invention provides an electrolyte analysis test strip for measuring a concentration of ions contained in an electrolyte. The electrolyte analysis test strip includes a substrate extending in one direction. An ion sensitive electrode is provided in specific regions on a side of one end in the one direction on a main surface of the substrate. A main extraction electrode extends from the ion sensitive electrode to a side of an other end. A solution detection electrode is provided in a proximal region in a manner separated from the main extraction electrode, and is for detecting whether or not the solution detection electrode is in contact with the electrolyte. An auxiliary extraction electrode extends from the solution detection electrode to the side of the other end in a manner separated from the main extraction electrode.

    IPC: G01N27/333

    CPC classification number: G01N27/333

    Abstract: An electrolyte analysis device includes a substrate extending in one direction, a main base portion provided on a main surface of the substrate, an ion selective film provided to be in contact with the main base portion so as to cover the main base portion, and an auxiliary base portion provided on the substrate. In a state where the electrolyte is in contact with a side of one end of the substrate so as to cover the side of the one end, a peeling determination unit obtains a potential of the main base portion and a potential of the auxiliary base portion, respectively. Whether or not the ion selective film is peeled from the main base portion is determined based on a potential difference between an obtained potential of the main base portion and an obtained potential of the auxiliary base portion.

    IPC: G01N27/333

    CPC classification number: G01N27/333

    Abstract: The present invention relates to a Solid-Contact Ion-Selective Electrode (SC-ISE) and a method of producing a SC-ISE. The SC-ISE of the invention comprises at least one transition metal in a mixed redox state and is suitable for long-term deployment having a long term stability and thus limited need for calibration.

    Abstract: The present invention is provided with an electrolyte measurement unit 11, a second measurement unit for performing measurement of a different measurement item to the electrolyte measurement unit 11, a sampling mechanism 5 for dispensing a sample to the electrolyte measurement unit 11 or the second measurement unit, and a control unit 13 for controlling the operation of respective devices. When the sample is dispensed to the second measurement unit by the sampling mechanism 5 or measurement of the sample is performed by the second measurement unit, the control unit 13 measures the potential in a state in which ion-selective electrodes 104, 105, and 106 are filled with an internal standard liquid, and determines, on the basis of measured data, whether or not there is an abnormality in the electrolyte measurement unit 11. An electrolyte analysis device capable of sensing an unstable state at an early stage, and a method for determining an abnormality in an electrolyte concentration measurement unit, are thereby provided.

    Abstract: An embodiment provides a method for measuring an analyte of a sample, including: introducing a sample to a sample region of a measurement device; the measurement device comprising: a measurement electrode and a ground electrode contacting the sample; a low-slope reference electrode in a reference electrode assembly having an electrolyte solution, wherein the electrolyte solution is in contact with the low-slope reference electrode; wherein the electrolyte solution is electrically coupled to the sample via at least one junction; and measuring a first potential between the measurement electrode and the ground electrode; measuring a second potential between the low-slope reference electrode and the ground electrode; determining an analyte in the sample by comparing the first potential and the second potential. Other aspects are described and claimed.

    Abstract: A considerable amount of time is required for calibration and compliance service for electrolyte measuring devices with ion selective electrode analyzers in most clinical or diagnostic laboratory settings. Often a user has to make trade-offs between improving diagnostic accuracy and processing higher workloads faster and more predictably. Current electrolyte measuring devices with ion selective electrodes are unable to balance the increased requirements for accuracy and speed. The presently claimed and described technology provides an improved device for an ion selective electrode analyzer. The presently claimed and described technology also provides methods for simultaneous and selective washing of components of the ion selective electrode analyzer and methods for simultaneous and selective analysis of samples using the ion selective electrode analyzer in an automated chemical analyzer.
