LiChrospher® RP-Select B (5 µm) HPLC Columns
MilliporeSigma offers a broad range of HPLC columns that are fully compliant with USP (United States Pharmacopoeia) specifications. L7 USP columns are described as octyl silane (C8), chemically linked to porous silica particles, 1.5 to 10 µm in diameter. Our high-quality L7 USP columns include: LiChrospher® RP-Select B (5 µm).
LiChrospher® 60 RP-Select B (5 µm) 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 their elution as highly symmetrical peaks. LiChrospher® 60 RP-Select B is also suitable for the determination of neutral and acidic substances.
Several individual batches of LiChrospher® RP-select B are used to produce a large master batch. This ensures the sorbent’s excellent batch-to-batch consistency. Consequently, LiChrospher® RP-select B delivers highly reproducible results, and secures the reliability of your HPLC method.
The superior reproducibility of the “master batch LiChrospher® RP-select B" compared to small individual batches of the sorbent is demonstrated with the Tanaka test.
