LiChrospher
LiChrospher® is a reliable and versatile spherical silica sorbent manufactured by Merck, which is traditionally produced and available with different modifications.
LiChrospher® WP 300 RP-18 is a highly selective and reliable HPLC column for the separation of peptides and low molecular weight proteins. The column enables tailing-free separations of basic compounds, and is optimally suited for the separation of tRNA molecules.
LiChrospher® PAH is a highly selective and efficient HPLC column, which is specially designed for the trace analysis of PAH according to EPA 610 and EPA 550.
LiChrospher® 60 RP-Select B is a versatile reversed-phase sorbent optimized for HPLC separations of basic compounds.
