Flash Chromatography¶
Rapid Peptide Purification¶
Category¶
Purification Equipment
Application¶
Initial purification of crude peptide, desalting
Function¶
Fast, lower-resolution purification using C18 silica under pressure.
Key Parameters¶
| Parameter | Typical Range |
|---|---|
| Column size | 5–100 g silica |
| Flow rate | 10–100 mL/min |
| Particle size | 20–40 μm |
| Pressure | 5–20 bar |
Advantages¶
- Faster than preparative HPLC
- Lower solvent consumption
- Good for initial purity upgrade (60% → 85%)
Limitations¶
- Lower resolution than HPLC
- Higher product loss
- Not suitable for final purification to ≥98%
