Note:Comparision of column diameter on preparative separations using Axia-packed columns in various diameters: 4.6 (conventional hardware), 21.2, 30 and 50mm (cf: App IDs: 18062 - 18065).
Load varied by diameter as follows:
- 4.6mm: 64 µg in 21 µL DMSO (scaling factor = 1)
- 21.2mm: 1.2 mg in 420 µL DMSO (scaling factor = 20)
- 30mm: 2.4 mg in 840 µL DMSO (scaling factor = 40)
- 50mm: 7.3 mg in 2100 µL DMSO (scaling factor = 118)
