LiChrospher® 60 RP-Select B is a versatile reversed-phase sorbent optimized for HPLC separations of basic compounds. Based on spherical silica particles, the sorbent prevents secondary interactions with basic substances, and ensures that they are eluted as highly symmetrical peaks. Besides offering excellent separation properties for basic compounds, LiChrospher® 60 RP-Select B is also suitable for the determination of neutral and acidic substances.
