Introduction

1. Standard background and technological evolution

GB/T 30430-2019 replaces the old version GB/T 30430-2013, and has made important revisions to the technical requirements and test methods for standard chromatographic columns used in gas chromatograph testing. The new version adds the terms and formulas, indicators and test methods for separation, and modifies the column length and its error parameters, while deleting some outdated content such as the terms related to "large-diameter capillary columns".

2. Classification and technical requirements of standard chromatographic columns

Classification of standard columns	Column inner diameter (mm)	Film thickness of stationary liquid (μm)	Column length (m)	Material	Stationary phase ratio/stationary liquid
Packing column	2.0±0.1	-	0.6±0.1	Stainless steel	5% polydimethylsiloxane/acid-washed silanized white diatomaceous earth support (125μm～150μm)
Capillary column	0.25、0.32	0.25	30.0±0.1	Quartz capillary	Polydimethylsiloxane

3. Implementation suggestions and practical application cases

Implementation suggestions:

When selecting a standard chromatographic column, its technical parameters should be matched according to specific detection requirements.
For newly purchased standard columns, they should be tested and verified in strict accordance with standard requirements.
In daily use, it is recommended to calibrate the instrument regularly and record relevant performance indicators.
