LiChrosorb® RP-18 (5 µm) HPLC Columns and Sorbents

MilliporeSigma offers a broad range of HPLC columns that are fully compliant with USP (United States Pharmacopoeia) specifications. L1 USP columns are described as octadecyl silane, chemically linked to porous silica or ceramic micro particles. Our high-quality L1 USP products deliver reliable, reproducible results – time after time. A perfect example is: LiChrosorb® RP-18 (5 µm).

Packing Materials for a Successful Start

LiChrosorb® is one of the most successful HPLC packing materials on the market. Its use in thousands of chromatography applications has been documented for more than 35 years. The totally porous irregular particles of LiChrosorb® RP-18 (5 µm) are made of silica with an octadecyl derivative. This highly reliable sorbent is suitable for reversed-phase HPLC of neutral, acidic and weak basic compounds, according to L1 USP specifications.
