1.1 本规程涵盖了电子捕获检测器（ECD）作为气相色谱系统检测组件的使用。 1.2 本规程旨在描述ECD的操作和性能，作为其在完整色谱系统中使用的指南。 1.3 一般气相色谱程序的实施规程 E260 或练习 E1510 除非本实施规程中建议对ECD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，请参阅实践 E355页 . 这些标准还描述了检测器的性能，当检测器与色谱柱和其他色谱成分耦合时，分析员可以使用这些性能来预测整体系统性能。 1.4 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。 1.5 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。 有关具体安全信息，请参阅第节 3. . 1.6 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。

1.1 This practice covers the use of an electron-capture detector (ECD) as the detection component of a gas chromatographic system. 1.2 This practice is intended to describe the operation and performance of the ECD as a guide for its use in a complete chromatographic system. 1.3 For general gas chromatographic procedures, Practice E260 or Practice E1510 should be followed except where specific changes are recommended in this practice for use of an ECD. For a definition of gas chromatography and its various terms, see Practice E355 . These standards also describe the performance of the detector in terms which the analyst can use to predict overall system performance when the detector is coupled to the column and other chromatographic components. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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. For specific safety information, see Section 3 . 1.6 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.
