Accessories (Sample pretreatment, parts)
Name: Accessories (Sample pretreatment, parts)
Description:One of the causes of a gradual increase of a column pressure after each sample injection is that fine particles in the sample clog the frit of the column. Replacing the column frit is one solution; however it is more convenient to use precolumn filter. Connect a precolumn filter between the injector and the column, check the line pressure occasionally, and replace the precolumn filter when the line pressure increases. Stainless steel precolumn filters are suitable for stainless steel tubing systems. Both PEEK and stainless steel precolumn filters are suitable for PEEK tubing systems.
Polysaccharide Derivatives Chiral Columns (Normal Phase)
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.
Polysaccharide derivatives Solvent-based chiral columns (bonded chiral columns)
Name: Polysaccharide derivatives Solvent-based chiral columns (bonded chiral columns)
Description:Polysaccharide derivatives Solvent-based chiral columns(bonded chiral columns)
Polysaccharide derivative coated chiral column (reversed phase)
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.
CHIRALPAK?AGP, CHIRALPAK?CBH, CHIRALPAK?HAS
Name: CHIRALPAK?AGP, CHIRALPAK?CBH, CHIRALPAK?HAS
Description:The protein-bonded chiral column was renamed from January 1, 2010.
Special chiral column
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
Mitsubishi Chemical Ligand Exchange Chiral column
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.
OA-3000 series column
Name: OA-3000 series column
Description:OA-3000 Series columns are effective in separating carboxylic acid compounds, especially acetyl and polyurethane amino acid compounds. The OA-3300 columncan directly separate ibuprofen, acetamino acid, BOC-amino acid and benzyl amino acid.
OA-2000 series column
Name: OA-2000 series column
Description:OA-2000 series column can be directly separated aromatic, esters, carboxylic acids and alcohol compounds isomers, such as OA-2000 column synthesis of pyrethrins, OA-2500 separable ibuprofen drugs
OA-4000 series column
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.
