Preparative LC ColumnsRelationship between Column I.D. , Sample Loading Volume and Flow Rate.
In preparative operations, column internal diameter sizes from 6.0 to 100 mm are widely used. When the analytical conditions along with the column packing material and length were the same between the analytical and preparative run, nearly the same chromatograms can be achieved by simply adjusting the flow rate and sample loading volume in proportion to the column cross-section area.
The following table illustrates the appropriate flow rate against each column internal diameter sizes.
InertSustain and Inertsil preparative columns are available in a broad range of column sizes to answer and meet all demands in preparative chromatography.
