A chromatographic column can be used both for manual analysis and as part of a chromatograph. It is responsible for separation and is therefore a key component of chromatography systems.
In terms of appearance, columns may take the form of a straight, curved or U-shaped tube, or other shapes. Depending on the material used, they may be made of glass or metal.
Key parameters to consider when selecting a column:
- the nature and thickness of the stationary phase
- column length
- inner diameter
