Chiral Carbohydrate Adducts are Effective for Enantiomeric Ion Mobility Separations. [PDF]

open access: yesJ Am Soc Mass Spectrom
Enantiomers play important roles in biology and the pharmaceutical industry but remain notoriously difficult to separate and characterize. Gold-standard chromatography and nuclear magnetic resonance-based methods are slow, laborious, and expensive ...

Orthogonal assembly of hetero-porous structures by reversible adaptation for efficient isomeric separation [PDF]

open access: yesNature Communications
Isomers separation is a challenging but crucial process in biological and chemical processes. Mixed-matrix membranes (MMMs) combining selective adsorbents within the polymer matrix have the potential for separating isomeric mixtures. However, the limited

Evaluation and Application of Stationary Phase Selectivity for Drug Analysis [PDF]

open access: yes
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 ...

Analytical Separation of Closantel Enantiomers by HPLC [PDF]

open access: yesMolecules, 2021
Closantel is an antiparasitic drug marketed in a racemic form with one chiral center. It is meaningful to develop a method for separating and analyzing the closantel enantiomers. In this work, two enantiomeric separation methods of closantel were explored by normal-phase high-performance liquid chromatography.

Synthesis of charged cyclodextrin highly soluble in organic solvents for enantiomer separations in capillary electrophoresis [PDF]

open access: yes, 2006
Synthesis of charged cyclodextrin highly soluble in organic solvents was made by exchanging the inorganic counter ion (Na+) of heptakis (2,3-di-Omethyl- 6-O-sulfo)-ò-CD (Na7HDMS) with tetrabutylammonium (TBA+), to produce TBA7HDMS.

Enantioselective Separation of Mirtazapine and Its Metabolites by Capillary Electrophoresis with Acetonitrile Field-Amplified Sample Stacking and Its Application

open access: yesMolecules, 2014
A simple, rapid and sensitive chiral capillary zone electrophoresis coupled with acetonitrile-field-amplified sample stacking method was developed that allows the simultaneous enantioselective separation of the mirtazapine, N-demethylmirtazapine, 8 ...
