Product details
B-DAFixed phase bonding of capillary columnsβ-Cyclodextrin derivatives(2,6-di-O-pentyl-3-methoxy). It can effectively separate heterocyclic amines and has a different selectivity from other stationary phases, starting from the pH stage and exhibiting reverse phase characteristics in the washing process.
MAOT = 200?℃ (constant temperature line)?220?℃ (program temperature)
Temperature limit:-10°Cto200 °CIsothermal temperature,The program temperature can be set to220 °C
CHIRALDEX B-DARequire the analyte to have at least two cyclic structures,One of them is unsaturated connecting chiral centers(Aromatic)α、βFor example, fluoxetine, methylphenidate, and chlorpheniramine.DAThe main mechanism of series enantioselectivity is the appropriate encapsulation and coordination between the analyte and the cyclodextrin cavity. There must be an enveloping group connecting the chiral centerαorβUsed for chiral recognition. becauseCHIRALDEX DAColumn can efficiently separate polycyclic analytes,Therefore, the analysis temperature is usually higher than150°CAt the temperature>200°CWhen stereoselective enantioselectivity can be observed(Acetyl derivatives of fluoxetine).
