1.1 本规程涵盖了用作气体或超临界流体色谱系统检测组件的火焰离子化检测器（FID）的性能测试。 1.2 本推荐规程直接适用于采用氢-空气或氢氧火焰燃烧器和直流偏置电极系统的氢火焰离子化检测器。 1.3 本推荐规程涵盖了检测器本身的性能，独立于色谱柱、色谱柱与检测器接口（如有）和其他系统组件，当检测器成为完整色谱系统的一部分时，分析员可以使用这些组件来预测整体系统性能。 1.4 一般气相色谱程序的实施规程 E260 除非本文建议对FID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，请参阅推荐规程 E355页 . 1.5 有关FID原理、结构和操作的一般信息，请参阅参考文献 ( 1. , 2. , 3. , 4. ) . 2. 1.6 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。 1.7 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 5. . 1.8 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====== 4.1 虽然可以在不同和独特的条件下观察和测量探测器的各种特性，但本推荐做法的目的是在相同的操作条件下获得一整套探测器规范，包括几何形状、流速和温度。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。本推荐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。 4.2 氢火焰离子化检测器通常仅用于非电离超临界流体作为流动相。 因此，本标准不包括超临界流体中改进剂的使用。 4.3 使用的记录系统或其他数据采集设备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，Bonsall ( 5. ) 还有McWilliam ( 6. ) 特别是，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 the testing of the performance of a flame ionization detector (FID) used as the detection component of a gas or supercritical fluid (SF) chromatographic system. 1.2 This recommended practice is directly applicable to an FID that employs a hydrogen-air or hydrogen-oxygen flame burner and a dc biased electrode system. 1.3 This recommended practice covers the performance of the detector itself, independently of the chromatographic column, the column-to-detector interface (if any), and other system components, in terms that the analyst can use to predict overall system performance when the detector is made part of a complete chromatographic system. 1.4 For general gas chromatographic procedures, Practice E260 should be followed except where specific changes are recommended herein for the use of an FID. For definitions of gas chromatography and its various terms see recommended Practice E355 . 1.5 For general information concerning the principles, construction, and operation of an FID, see Refs ( 1 , 2 , 3 , 4 ) . 2 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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 5 . 1.8 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 ====== 4.1 Although it is possible to observe and measure each of the several characteristics of a detector under different and unique conditions, it is the intent of this recommended practice that a complete set of detector specifications should be obtained at the same operating conditions, including geometry, 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 recommended practice are sufficiently general so that they may be used at whatever conditions may be chosen for other reasons. 4.2 The FID is generally only used with non-ionizable supercritical fluids as the mobile phase. Therefore, this standard does not include the use of modifiers in the supercritical fluid. 4.3 Linearity and speed of response of the recording system or other data acquisition device used should be such that it does not distort or otherwise interfere with the performance of the detector. Effective recorder response, Bonsall ( 5 ) and McWilliam ( 6 ) , in particular, 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.
