Chiral stationary phases and applications in gas chromatography [PDF]
Chirality, 2022 AbstractChiral compounds are ubiquitous in nature and play a pivotal role in biochemical processes, in chiroptical materials and applications, and as chiral drugs. The analysis and determination of the enantiomeric ratio (er) of chiral compounds is of enormous scientific, industrial, and economic importance.

Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]
Despite the wide range of HPLC stationary phases available for reversed-phase high-performance liquid chromatography (RP-HPLC) and the in-depth studies using probes to highlight differences between them, there is very little in the way of stationary ...

An Evaluation of Immobilized Poly-(S)-N-(1-phenylethyl)acrylamide Chiral Stationary Phases
Separations, 2022 In this study, brush type and polymer type stationary phases were prepared based on (S)-N-(1-phenylethyl) acrylamide, and the polymeric stationary phase demonstrated superior chiral recognition ability.

Application of Natural and Modified Biomacromolecules in Miniaturised Separative Analytical Techniques [PDF]
In pharmaceutical R & D, drug stereochemistry, and consequently the rotation of enantiomers, is very important. Because they act as chiral selectors in vivo, biomacromolecules have been extensively used as chiral selectors for the liquid chromatographic (

Optically active distorted cyclic triptycenes: chiral stationary phases for HPLC. [PDF]
RSC Adv, 2018 We have succeeded in developing triptycene-based chiral stationary phases with a distorted cyclic structure, which can resolve a series of axially chiral compounds.

Separation of propranolol enantiomers using chiral HPLC [PDF]
Kragujevac Journal of Science, 2023 Enantiomers of pharmaceuticals may exhibit different effects because the organism serves as a chiral selector. Enantiomers can now be identified and separated using analytical techniques such as gas chromatography and high-performance liquid ...
