L-column series is the column for reversed-phase high-performance liquid chromatography (RP-HPLC) that enabled separation only by hydrophobic interaction because of inhibition of the secondary interaction with residual silanol groups and metal impurities.

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.


L1: Octadecyl silane chemically bonded to porous or non-porous silica or ceramic micro-particles, 1.5 to 10 μm in diameter, or a monolithic rod.
