本文将使读者熟悉用于描述离子选择性电极行为的术语，特别是与其在临床化学中用于测定血液电解质阳离子有关的术语。它是一系列关于血液中重要阳离子（即钙、钠和钾）的论文的介绍。用流程图和方程描述了用离子选择性电极电位法在未稀释样品中测定的离子活度与用火焰原子发射光谱法测定的总物质浓度之间的详细关系。建议通过一项报告结果的惯例，选择性电极工作组考虑到了国际化联最近对离子选择性电极命名和选择性系数测定建议的修订，并从工作组一名成员的经验中获益，他也参与了国际化联的讨论。确定数量的命名遵循IUPAC/IFCC先前的联合建议。
This paper will familiarize the reader with the terms used to describe the behavior of ion-selective electrodes, particularly in relation to their use in clinical chemistry for determination of blood electrolyte cations. It serves as an introduction to a series of papers dealing with important cations in blood, namely calcium, sodium, and potassium. The detailed relationships between the ion activity determined by means of ion-selective electrode potentiometry in undiluted specimens, and the total substance concentration measured by flame atomic-emission spectrometry are described by flow chart and equations. Adoption of a convention for reporting results is recommended.The Working Group on Selective Electrodes has taken into account recent revisions of IUPAC recommendations on nomenclature and selectivity coefficient determinations for ion-selective electrodes, and benefited from the experience of a member of the WG, who was also involved in the IUPAC discussions. Nomenclature for determined quantities follows previous IUPAC/IFCC joint recommendations.
