Flash Chromatography
Flash Chromatography — A rapid column chromatography technique using compressed gas to push solvent through the column, providing faster peptide separation than gravity-based methods.
What Is Flash Chromatography?
Flash chromatography is a rapid, medium-pressure column chromatography technique using pre-packed silica or C18 cartridges with air/pump-driven solvent flow. In peptide chemistry, flash chromatography provides fast crude purification of protected peptide segments, amino acid derivatives, and small-molecule reagents.
Applications
- Crude cleanup: Rapid removal of gross impurities before HPLC purification
- Building blocks: Purification of Fmoc-amino acid derivatives and coupling reagents
- Scale: Gram to multi-gram. Faster and less expensive than preparative HPLC for crude separations
