Reversed-phase HPLC is normally the method of choice for purification of crude synthetic peptides. However, the purification step is one of the main bottlenecks in the peptide synthesis workflow. High performance flash chromatography is a very efficient technique to dramatically clean-up synthetic peptides. Biotage® Sfär Bio flash columns were developed with a small particle size (20 μm) and large pore size (300 Å) to provide increased resolution and the effective separation of complex peptide mixtures. Depending on the quality of the peptides synthesized, flash chromatography can be used either as the sole method of purification or as a front end clean-up prior to RP-HPLC.
The increased loading capacity of Biotage® Sfär Bio flash columns allows more peptide to be processed in a single injection, compared to preparative RP-HPLC. The increased loading capacity also brings a consequent reduction in solvent usage and waste production compared to RP-HPLC (per mg of purified peptide). Biotage® Sfär Bio offers close to prep-HPLC performance, in a flash format at a fraction of the cost. Additionally, Sfär Bio columns are chemically neutral with high chemical resistance, tested at high and low pH for robustness and reliability.

Biotage Sfär columns are available as C18 and C4 media - C4 is slightly more polar than C18, and therefore the selectivity of C4 is increased for smaller and more polar molecules. Read more about their suitability...
