    Can I improve my peptide purification by increasing the column length?

    There are several strategies often employed to improve peptide purity achieved using reversed phase HPLC.  These strategies can include, changing column length, particle size, particle functionality (C4 vs C18).  I have experimented a bit with some of these criteria while purifying peptides using reversed phase flash chromatography but one obvious change that I have not yet explored is the length of column.

    In today's post, I'll explore how the length of the cartridge affects the overall resolution and purification efficiency using reversed phase flash column chromatography.
