1.1 本规程主要涉及液相色谱中使用的术语和关系。然而，大多数术语也应适用于其他种类的液相色谱，尤其是平面色谱，如纸色谱或薄层色谱。 注1: 虽然电泳也可以被视为一种液相色谱技术，但它及其相关术语尚未包括在本实践中。 1.2 由于大多数基本术语和定义也适用于气相色谱法，因此本规程尽可能使用与规程相同的符号 E355页 . 1.3 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。 1.4 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。

1.1 This practice deals primarily with the terms and relationships used in liquid column chromatography. However, most of the terms should also apply to other kinds of liquid chromatography, notably planar chromatography such as paper or thin-layer chromatography. Note 1: Although electrophoresis can also be considered a liquid chromatographic technique, it and its associated terms have not been included in this practice. 1.2 Since most of the basic terms and definitions also apply to gas chromatography, this practice uses, whenever possible, symbols identical to Practice E355 . 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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.
