临床化学中的离子选择电极临床关系电解质是可在水溶液中离解成离子的化合物。对人体有机组织中液体的测定可用于说明它们的分布,尤其可确定液体是在细胞内还是在细胞外。在细胞外液体阳离子中,Na~+占主要部分,其次为K~+,Ca~(2+)和Mg~(2+);阴离子中Cl~-占主要部分,其次为HCO_3~-。在细胞内的液体其离子种类与细胞外的液体差别很大。在细胞内的阳离子大多数为K~+(整个人体中有98％ Ion-selective electrodes in clinical chemistry Clinical relationships Electrolytes are compounds that dissociate into ions in aqueous solutions. The determination of liquids in organic tissues of the human body can be used to illustrate their distribution, in particular whether the liquid is intracellular or extracellular. Among the extracellular liquid cations, Na ~ + accounted for the major part, followed by K ~ +, Ca ~ (2+) and Mg ~ (2+); Cl ~ - in the anion accounted for the major part, followed by HCO_3 ~ -. The type of liquid in the cell varies greatly from that of the extracellular fluid. Cation in the cells most of K ~ + (98% of the entire human body,
