1.1 本规程包括计算气相色谱响应系数的程序。它适用于从气体混合物或在室温和压力下通常为液体的任何化合物混合物或与液体形成溶液的固体或两者中获得的色谱数据。它不适用于那些在色谱仪中反应或未定量洗脱的化合物。正常C 6. 通过C 11 出于演示目的，已选择石蜡作为模型化合物。 1.2 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。 1.3 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。 1.4 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====== 5.1 ASTM石油产品分析的标准气相色谱法要求通过制备和分析指定的参考混合物来校准气相色谱系统。通常，这些方法在计算校准或响应系数的实践中提供的信息最少。试验方法 D2268 , D2427 , D2804 , D2998 , D3329页 , D3362 , D3465 , D3545 和 D3695 都是例子。本实践通过提供计算响应系数的详细参考程序，有助于填补这一空白，例如C的标准混合物的分析 6. 至C 11 n -石蜡使用 n -C 12 作为稀释剂。 5.2 在实践中，响应因子用于在最终计算样品成分之前将峰面积校正到公共基数。本规程中计算的响应系数为“乘数”，在最终计算结果之前，样品中每种化合物的面积应乘以该化合物的响应系数。 5.3 已经确定，响应系数的值将随单个安装而变化。 这可能是由仪器设计、色谱柱和实验技术的变化引起的。有必要对色谱仪进行单独校准，以获得最准确的数据。

1.1 This practice covers a procedure for calculating gas chromatographic response factors. It is applicable to chromatographic data obtained from a gaseous mixture or from any mixture of compounds that is normally liquid at room temperature and pressure or solids, or both, that will form a solution with liquids. It is not intended to be applied to those compounds that react in the chromatograph or are not quantitatively eluted. Normal C 6 through C 11 paraffins have been chosen as model compounds for demonstration purposes. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. 1.4 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 ====== 5.1 ASTM standard gas chromatographic methods for the analysis of petroleum products require calibration of the gas chromatographic system by preparation and analysis of specified reference mixtures. Frequently, minimal information is given in these methods on the practice of calculating calibration or response factors. Test Methods D2268 , D2427 , D2804 , D2998 , D3329 , D3362 , D3465 , D3545 , and D3695 are examples. The present practice helps to fill this void by providing a detailed reference procedure for calculating response factors, as exemplified by analysis of a standard blend of C 6 to C 11 n -paraffins using n -C 12 as the diluent. 5.2 In practice, response factors are used to correct peak areas to a common base prior to final calculation of the sample composition. The response factors calculated in this practice are “multipliers” and prior to final calculation of the results the area obtained for each compound in the sample should be multiplied by the response factor determined for that compound. 5.3 It has been determined that values for response factors will vary with individual installations. This may be caused by variations in instrument design, columns, and experimental techniques. It is necessary that chromatographs be individually calibrated to obtain the most accurate data.
