Molecularly imprinted monolithic stationary phases for liquid chromatographic separation of enantiomers and diastereomers.
The method for preparation of molecularly imprinted monolithic stationary phase has been improved to achieve liquid chromatographic separation of enantiomers and diastereomers. By adopting low polar porogenic solvents of toluene and dodecanol and optimal polymerization conditions, the molecularly imprinted monolithic stationary phases with good flow-through properties and high resolution were p...
متن کاملComparing monolithic and fused core HPLC columns for fast chromatographic analysis of fat-soluble vitamins.
HPLC stationary phases of monolithic and fused core type can be used to achieve fast chromatographic separation as an alternative to UPLC. In this study, monolithic and fused core stationary phases are compared for fast separation of four fat-soluble vitamins. Three new methods on the first and second generation monolithic silica RP-18e columns and a fused core pentafluoro-phenyl propyl column ...
متن کاملChromatographic Separation of the Diastereoisomers
Reduction of folic acid to the tetrahydro level introduces a second asymmetrical center into the molecule at carbon atom 6.1 The resulting tetrahydrofolate, and subsequent derivatives, prepared chemically consist of dl mixtures that are only 50% active in biological reactions. The need for fully reactive isomers of reduced folates led to the enzymatic synthesis of tetrahydrofolate from 7, %dihy...
متن کاملFunctional monolithic platforms: chromatographic tools for antibody purification.
Polymer monoliths are an efficient platform for antibody purification. The use of monoclonal antibodies (mAbs) and engineered antibody structures as therapeutics has increased exponentially over the past few decades. Several approaches use polymer monoliths to purify large quantities of antibody with defined clinical and performance requirements. Functional monolithic supports have attracted a ...
متن کاملMoment analysis of chromatographic behavior of separation media for fast HPLC.
The van Deemter equation and moment equations were used for analyzing the flow rate dependence of HETP experimentally measured in order to clarify chromatographic behavior from the kinetic points of view in columns packed with C18-silica monolith and C18-core-shell particles under RPLC conditions. They provided some information about molecular diffusion, eddy diffusion, and mass transfer kineti...
