Based on 5μm spherical sodium magnesium silicate particles, Ceramospher phases RU-1 and RU-2 are novel materials for chiral HPLC separations. Chiral separation is accomplished by an optically-active ruthenium complex that has been ion exchanged with sodium ions in the original clay material. Ceramospher phases show excellent selectivity for a wide variety of chiral samples. Ceramospher has the remarkable loadability due to its large specifi c surface area (pore size 4nm, 300m2/g). The advantage is more pronounced when applied at preparative scales.
Both phases utilize simple eluents.RU-1 is used under non-aqueous mobile phases, whereas RU-2 is compatible also with aqueous mobile phases.
