General description

LiChrosorb® RP-18 HPLC Column are classified as L1 USP columns and primarily used for reversed-phase HPLC of neutral, acidic and weak basic compounds. The totally porous irregular particles ensure reliable results.
LiChrospher® RP-18 HPLC column is an incredibly reliable and highly versatile, traditionally manufactured spherical silica-based support, designed for reversed-phase chromatography of acidic, neutral and weakly basic compounds - substances frequently found in all analytical fields. The optimal selectivity and performance of the column ensure that these parameters remain constant from batch to batch and from year to year.
