L-column ODS-P is ideal for the analysis of proteins and peptides. The base silica has a pore diameter of 30 nm. Adsorption is minimized and proteins and peptides elute with sharp peaks. Biological samples are often analyzed using 1 % TFA in the mobile phase and L-column ODS-P is exceptionally stable in strongly acidic mobile phase.
