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 basic compounds are eluted as symmetrical substance peaks. Furthermore LiChrospher® RP-select B is comprehensively tested to comply with a selectivity specification and the retention and separation factors are fixed in a reproducibility guarantee.
