Abstract: Provided is an electrolyte analyzing device in which contamination caused by contacting different reagents with a suction nozzle is prevented when reagent replacement is performed by a user. The electrolyte analyzing device includes a reagent container setting unit 502 that sets a dilute solution bottle 101-1 which houses a dilute solution, an internal standard solution bottle 101-2 which houses an internal standard solution, and a reference electrode solution bottle 101-3 which houses a reference electrode solution. The reagent container setting unit includes a partition wall between the dilute solution bottle 101-1 and the internal standard solution bottle 101-2, and the reference electrode solution bottle 101-3 when the dilute solution bottle 101-1, the internal standard solution bottle 101-2, and the reference electrode solution bottle 101-3 are set.

Abstract: There is disclosed a precious metal article which is formed of a solid-phase sintered product of a precious metal powder. For manufacturing the precious metal article, a moldable mixture which contains a precious metal powder and a binder removable by sintering is shaped into a prescribed molded object, and the molded object is then subjected to sintering. The moldable mixture is produced by preparing a precious metal powder, preparing a jellylike cellulose binder by blending a cellulose with water and leaving for a prescribed period of time, and blending the precious metal powder and the jellylike cellulose binder together. The most preferable moldable mixture contains 50 to 90% by weight of precious metal powder, 0.8 to 8% by weight of water-soluble cellulose binder, 0.08 to 3% by weight of a surface-active agent. 0.1 to 3% by weight of oil, balance water and unavoidable impurities.
