  • Publication number: 20210010970
    Abstract: There is provided an electrolyte measuring device that can decrease a liquid amount used for measurement, in which stable sealing can be provided in connecting passages of ion selective electrodes to each other with no gap, while maintaining high measurement accuracy of an existing ion selective electrode, and a residing sample liquid can be greatly decreased. In a flow-type ion selective electrode, a sealing member is used, which can be brought into intimate contact with a passage connecting unit to near a passage hole. A gap regulating member is provided to keep a gap between the electrodes constant and to prevent the sealing member from being excessively pressed. An electrode case has a structure suitable for the sealing member for allowing the alignment and holding of the sealing member.

  • Patent number: 10234416
    Abstract: The present invention announces a method for extending the storage life of a test reagent for quantification of ionic components in samples by using an anion sensor. The purpose of the present invention is to provide an anion sensor, wherein the storage life of the anion sensor itself may be extended, to thereby extend the storage life of the anion sensor beyond that of conventional anion sensors. According to the present invention, through adjustment of the pH of the internal solution (internal gel liquid), it is possible to provide an anion sensor that maintains consistent performance, and has longer storage life.

  • Publication number: 20180238829
    Abstract: The separation between an ion concentration measuring time period and an information read/write time period is not considered in existing devices. Therefore, in the present invention, the time period for retrieving information from a semiconductor memory mounted in a cartridge and the time period for measuring the concentration of ions are controlled so as not to overlap each other.
