LiChrospher® DIOL is a versatile HPLC sorbent based on spherical silica particles possessing both polar and hydrophobic properties. LiChrospher® DIOL may be used as weakly hydrophobic sorbent in reversed phase chromatography with some limitations or as polar sorbent in normal phase chromatography. LiChrospher® DIOL is also suitable for exclusion chromatography.

A versatile sorbent for both reversed phase and straight phase chromatography: LiChrospher® NH2 is a versatile HPLC sorbent based on spherical silica particles possessing both polar and hydrophobic properties. LiChrospher® NH2 may be used for normal phase chromatography, reversed phase chromatography and for ion exchange chromatography. Typical applications are the separation of carbohydrates (mono-, di- and oilgosaccharides)…

LiChrospher® PAH is a highly efficient and selective HPLC column especially designed for the high resolution separation of 16 PAH (polycyclic aromatic hydrocarbons) according to EPA 610 and 550 + benzo(e)pyrene + perylene. LiChrospher® PAH is based on a special modified RP-18 silica gel to achieve highly resolved PAH separations. LiChrospher® PAH can be used for both, the isocratic separation of 6 PAH according to the German…

For reproducible reversed phase separation: LiChrospher® RP-phases are reliable and versatile traditionally produced spherical silica carrier with reversed phase properties. They are well suited for the chromatography of acidic, neutral and weakly basic compounds, substances found frequently in all analytical fields. A selectivity and performance guarantee makes sure that these parameters remain constant form batch to batch a…

Excellent separations even with basic compounds: LiChrospher® RP-select B is a versatile reversed phase sorbent based on spherical silica particles with excellent properties for the determination of basic substances, but with still good properties for the determination neutral and acidic substances. LiChrospher® RP-select B is optimised in order to prevent any secondary interactions with basic substances and guarantees that…

High-resolution separations of peptides and tRNA molecules: LiChrospher® WP 300 RP-18 is a highly selective and reliable HPLC column for the separation of peptides and low molecular weight proteins. LiChrospher® WP 300 RP-18 enables the tailing-free separation of basic compounds and is excellently suited for the separation of tRNA molecules. High recovery rates are achieved, especially in the case of highly hydrophobic pepti…
