Application
|
| Particles for Preparative TLC Plates |
|
0 - 20 µm
|
•Contain neither binder (organic or inorganic) nor UV indicator (F254)
|
|
5 - 15 µm
|
•Can also be used in flash chromatography if higher resolution is required
(higher back-pressure)
|
|
5 - 20 µm
|
| Specialized Particles for Difficult Separations |
|
15 - 35 µm
|
•high-resolution silica for difficult separations (similar polarities)
|
|
15 - 40 µm
|
| Particles for Flash Chromatography |
|
40 - 63 µm
|
•Chromatography types: high-resolution flash chromatography & low to
medium-pressure preparative chromatography
|
| •Narrow particle size over other flash chromatography silica |
| •Easier to pack |
| •More uniform packing |
| •Superior resolution |
| •Suitable for uses with complex matrices |
|
60 - 120 µm
|
•Alternative to 40-63 µm silica gel for faster flow rate without pressure |
| Particles for column (or Gravity) Chromatography |
|
60 - 200 µm
|
•Most economical silica for open column chromatography (gravity) |
| •Suitable for rough purification and large-scale preparative chromatography |
| •Easier to handle |
| •Purification cost reduction |
|
120 - 200 µm
|
•Silica for standard open column chromatography |
| •Narrow particle size enables uniform packing |
| •Suitable for mass overload purification |
