| Particle Size Distribution |
Application |
| Particles for Preparative TLC Plates |
| From 0 to 20 μm |
- Contain neither binder (organic or inorganic) nor UV indicator (F254)
- Can also be used in flash chromatography if higher resolution is required (higher back-pressure)
|
| Particles for Difficult Separations |
| From 10 to 45 μm |
- high-resolution silica for difficult separations (similar polarities)
|
| Particles for Flash Chromatography |
| 40 - 63 µm |
- Chromatography types: high-resolution flash chromatography & low to medium-pressure preparative chromatography
- Narrow particle size distribution
- Easier to pack and more uniform packing
- Superior resolution
- Suitable for use with complex matrices
|
| 60 - 120 µm |
- Alternative to 40-63 µm silica gel for faster flow rate with lower pressure
|
| Particles for column (or Gravity) Chromatography |
| From 60 - 200 µm |
- Most economical silica for open column chromatography (gravity)
- Suitable for very dirty purification
- Easier to handle
|
| 120 - 200 µm |
- Silica for standard open column chromatography
- Narrow particle size distribution enables uniform packing
- Suitable for mass overload purification
|
| Other Application |
| From 200 to 1,000 µm |
