1.1This 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.

1.2Since most of the basic terms and definitions also apply to gas chromatography, this practice uses, whenever possible, symbols identical to Practice E355.

1.3The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4This 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.
