摘要： The present invention provides an ion selective electrode for anions such as Cl.sup.- and cations such as Ca.sup.2+ which has a sensitive membrane comprising a polymer material and containing an ion sensitive material and a plasticizer. In thins ion selective electrode, the ion sensitive material is an ion exchanger such as a quaternary ammonium salt, a quaternary phosphonium salt or an organic phosphate and the plasticizer is a compound having the formula (1): ##STR1## wherein X represents an alkyl group, a phenyl group or a phenyl group to which a functional group bonds. As the plasticizer there may also be used a mixture of the compound of the formula (1) with an alcohol compound such as an alcohol having a dielectric constant of 10 or less and containing 10 or more carbon atoms or an ester compound.

摘要： An anion-selective electrode of the present invention comprises, as anion sensitive substance, a tetraalkyl type, quaternary phosphonium salt having four alkyl radicals, each having 8 to 24 carbon atoms; a combination of a tetraalkyl onium salt having four alkyl radicals each having 10 to 24 carbon atoms, and an onium salt having one alkyl radical with 1 to 20 carbon atoms and three alkyl radicals with the proviso that the number of carbon atoms contained in the three alkyl radicals each is larger than that contained in the one alkyl radical; or a tetraalkyl type, quaternary onium salt having an asymmetrical molecular structure. The anion-selective electrode has good properties including selectivity and measurement accuracy. An anion-selective, field effect transistor or a chemical analysis apparatus, provided with the anion-selective sensitive substance, is suitable for measuring an anion concentration with a high accuracy.

摘要： Before analysis, the correspondence between the vessel positions and the reaction vessels held in the vessel positions respectively at the time of completion of all the operations of a turntable upon completion of the last analysis are stored in a computer in advance. When a start switch is turned on, a judgment is made as to whether the correspondences between the vessel positions and the reaction vessels coincide with those stored in the computer or not. In the case of coincidence, reaction vessels in vessel positions are regarded as having been already cleaned, so that these reaction vessels are subjected to blank measurement and sample addition in the case of optical measurement, whereas these reaction vessels are directly subjected to sample addition in the case of ISE measurement.
