This is a column for the separation of optical isomers, where cyclodextrin derivatives are chemically bonded to silica gel. It encapsulates solutes in the cavity of the molecule and distinguishes optical isomers through asymmetry in the sugar. OA-7000 uses sugar chains as spacers, resulting in superior separation ability and peak shape compared to conventional cyclodextrin stationary phases.

The OA-3000 series has a 3,5-dinitrophenylurea group as a Π acid, and chiral discrimination is performed through charge transfer and hydrogen bonding in a non-aqueous reverse phase.

• Analytical Equipment and Devices

The "Monolithic ODS Column Chromolith RP-18" manufactured by MERCK is a ligand-exchange type column for optical isomer separation, coated with the chiral selector SUMICHIRAL OA-5000. Monolithic HPLC columns use a cylindrical silica continuum instead of a 3-5 μm silica gel support. This silica continuum consists of a structure of macropores (approximately 2 μm) and mesopores (approximately 13 nm), with a high porosity of about 80%. By using this monolithic column as the substrate for the stationary phase of a chiral column, excellent characteristics can be achieved.

• Analytical Equipment and Devices

We manufacture and sell world-leading HPLC columns. The separation in high-performance liquid chromatography is greatly influenced by the characteristics of the column. Utilizing advanced technology and years of accumulated know-how, we support our customers from analysis to fractionation. The optical isomer separation column "SUMICHIRAL OA Series" has become an essential HPLC column in the pharmaceutical and pesticide fields. 【Features】 - Direct separation of optical isomers is possible, achieving excellent separation. - By changing the absolute configuration of the chiral selector in the column, the elution order of isomers can be reversed (excluding some columns). - The chiral selector is chemically stable as it is covalently bonded to silica gel (excluding some columns). We have launched a new product, 'OA-5000'. 【Features】 - The theoretical plate number has improved to 1.5 times that of conventional products (equivalent to a particle-filled column with a particle size of 3.5μm). - The column pressure is less than one-third of that of conventional products, allowing for increased flow rates during measurement. - Columns can be connected up to approximately 45 cm. - Ideal for analyzing samples with strong retention (such as dicarboxylic acids). *For details, please refer to "Request for Materials" or "Catalog Download."
