GB/T 30433-2013 stipulates the standard Chromatography Column for Liquid Chromatography (LC) testing. The standard specifies the classification and structural specifications of the standard Chromatography Column, specifies the parameter requirements such as column material, inner diameter and length in detail, and also specifies the type of Stationary phase and filling mass. At the same time, it specifies the Chromatography Column performance indicators, such as Theoretical plate, resolution and other test methods. It provides a unified standard Chromatography Column reference for Liquid Chromatography (LC) testing, ensures the comparability of test results between different laboratories, helps to improve the accuracy and Reliability of liquid chromatograph analysis, and promotes the development of related industries.
