1.1 本规程包括测试用作气相色谱系统检测组件的电解电导率检测器（ELCD）的性能。 1.2 本规程直接适用于电解电导率检测器，该检测器在氧化或还原条件下在镍催化剂表面上对给定样品进行化学反应，并在必要时使用洗涤器去除干扰，使用去离子溶剂溶解反应产物，以及用于测量电离反应产物的电解电导率的电导池。 1.3 本规程涵盖了检测器本身的性能，独立于色谱柱，当检测器与色谱柱和其他色谱系统组件耦合时，分析员可以使用其预测整体系统性能。 1.4 一般气相色谱程序的实施规程 E260 除非本文建议对电解电导率检测器的使用进行具体更改，否则应遵守。 有关气相色谱及其各种术语的定义，请参阅实施规程 E355页 . 1.5 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 3.1 虽然可以在不同和独特的条件下观察和测量ELCD的各种特性，特别是其不同的选择性模式，但本实践的目的是在相同的操作条件下获得一套完整的检测器规范，包括几何形状、气体和溶剂流速以及温度。 应注意的是，为了完全指定探测器的性能，应在探测器有效范围内的几组条件下测量其性能。本规程中描述的术语和测试具有足够的通用性，因此可以在出于其他原因选择的任何条件下使用。 3.2 所用记录器的线性度和响应速度应确保不会扭曲或干扰检测器的性能。有效记录器响应应足够快，以便在测量灵敏度方面可以忽略。如果在探测器和最终读出装置之间使用额外的放大器，也应首先确定其特性。

1.1 This practice covers testing the performance of an electrolytic conductivity detector (ELCD) used as the detection component of a gas chromatographic system. 1.2 This practice is directly applicable to electrolytic conductivity detectors that perform a chemical reaction on a given sample over a nickel catalyst surface under oxidizing or reducing conditions and employ a scrubber, if needed, to remove interferences, deionized solvent to dissolve the reaction products, and a conductivity cell to measure the electrolytic conductivity of ionized reaction products. 1.3 This practice covers the performance of the detector itself, independently of the chromatographic column, in terms that the analyst can use to predict overall system performance when the detector is coupled to the column and other chromatographic system components. 1.4 For general gas chromatographic procedures, Practice E260 should be followed except where specific changes are recommended herein for the use of an electrolytic conductivity detector. For definitions of gas chromatography and its various terms see Practice E355 . 1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 3.1 Although it is possible to observe and measure each of the several characteristics of the ELCD under different and unique conditions, in particular its different modes of selectivity, it is the intent of this practice that a complete set of detector specifications should be obtained at the same operating conditions, including geometry, gas and solvent flow rates, and temperatures. It should be noted that to specify a detector's capability completely, its performance should be measured at several sets of conditions within the useful range of the detector. The terms and tests described in this practice are sufficiently general so that they may be used at whatever conditions may be chosen for other reasons. 3.2 Linearity and speed of response of the recorder used should be such that it does not distort or otherwise interfere with the performance of the detector. Effective recorder response should be sufficiently fast so that it can be neglected in sensitivity of measurements. If additional amplifiers are used between the detector and the final readout device, their characteristics should also first be established.
