| 摘要 |
This invention relates to an ion analyzer of a multisensor type that can conduct an accurate analysis and that is easy to conduct maintenance. The ion analyzer has a liquid membrane type ion-selective electrode 71, 72 comprising multiple types of ion-sensitive membranes 15, 16 wherein each of multiple types of ionophores that selectively capture different ion is supported by a base material respectively, an internal solution 14c and a liquid junction 17 from which the internal solution 14c exudes, and the multiple types of the ion-sensitive membranes 15, 16 and the liquid junction 17 are arranged on the same supporting body, and at least one ion-sensitive membrane 16 among the multiple types of the ion-sensitive membranes 15, 16 is arranged outside of an area that is immersed in the internal solution 14c that exudes from the liquid junction 17. |
