This column-packing technology is based on a combination of vacuum suction with subsequent column bed compression that stabilises the packing. A common water-jet pump is used to generate the vacuum. The sorbent slurry is sucked through a packing reservoir into the column by applying low pressure at the bottom end of the column.

• Allows precise adjustment of the desired packing volume or sorbent bed height
• Facilitates the determination of the column geometry
• Makes direct scale-up from analytical to preparative scale easy
