GB/T 30430-2013 Standard Chromatography Column for Focused Gas Chromatograph Testing. It clarifies the category and structural style of such Chromatography Column, specifies the key size parameters such as column material, inner diameter and length in detail, and also provides specifications for Stationary liquid types, Coating thickness, etc. At the same time, the determination method of Chromatography Column Theoretical plate, resolution and other performance indicators is formulated. The standard provides a unified and standardized Chromatography Column basis for Gas Chromatograph testing, ensures the conformity and comparability of test results of different institutions, helps gas chromatograph analysis to be accurate and reliable, and promotes the standardization of detection work in related fields.
