Name: Polysaccharide Derivatives Chiral Columns (Normal Phase)
Description:Polysaccharide derivatives are the most widely used type of stationary phase in the world at present. The stationary phase is a spherical silica gel coated with a chiral polymer(amylose or cellulose derivative). Due to the physical coating, please pay attention to the choice of mobile phase.
Name: Polysaccharide derivatives Solvent-based chiral columns (bonded chiral columns)
Description:Polysaccharide derivatives Solvent-based chiral columns(bonded chiral columns)
Name: Polysaccharide derivative coated chiral column (reversed phase)
Description:The polysaccharide derivative-coated chiral column(reversed phase) is the same as the chiral polymer coated on the polysaccharide derivative-coated chiral column(normal phase), but it used different silica gel. Therefore, the mobile phase for the reverse phase system: water - organic solvents, suitable for LC-MS use.
Name: Special chiral column
Description:Solvent-based crown ether chiral column. This is a chemically bonded crown ether chiral column that uses all HPLC solvents. Based on the original high separation success rate of CROWNPAK®CR(+) / CR(-), it also has solvent resistance, which can avoid solvent damage to chiral column. And, you can use the more eluent solvent as the mobile phase, greatly reducing the analysis time
Name: Mitsubishi Chemical Ligand Exchange Chiral column
Description:The stationary phases of the MCI GEL CRS10W and MCI GEL CRS15W columns are silica(3 μm particle size, 100Å pore size) surface-bonded N, N-Dioctyl-L(D) -alanime. The mobile phase is copper sulfate aqueous solution. In the CRS10W column, the D configuration was eluted prior to the L configuration, but the L configuration was eluted prior to the D configuration on the CRS15W column. MCI GEL CRS10W and MCI GEL CRS15W columns not only separate alpha-amino acids but also alpha-hydroxy carboxylic acids.
Name: OA-4000 series column
Description:The OA-4000 Series columns achieve chiral recognition by charge-transfer and hydrogen-bond interactions and are capable of separating a wide variety of compounds such as amines and amino alcohols in pharmaceuticals, alcohols, esters and amides, It can be used the normal mode to Separated. In the separation of amide and polyurethane derivatives, alcohols, high efficiency is avalible.
Name: OA-5000 and OA-6000 series
Description:The OA-5000 and OA-6000 series columns perform chiral recognition in a reversed-phase mode by a coordination exchange interaction. OA-5000 chiral ligand is penicillamine coated on ODS silica gel surface. OA-6000 chiral ligand is tartaric acid derivative coated on the ODS silica gel surface, limiting the amount of organic solvent added to the mobile phase, and The mobile phase of the OA-5000 and OA-6000 series columns must contain Cu2 + ions. This series of columns not only effectively separates amino acids, enantiomers of hydroxy acids, but also separates compounds formed by copper chelation, such as aminoalcohols, amines, carboxylic acids, aminolactams and dipeptides. In particular, the OA-5000 column is extremely versatile and the OA-6000 is effective in separating β-amino acids, β-hydroxy acids and hydrophilic alminic acid.
