Chiral separations using gas chromatography
TrAC Trends in Analytical Chemistry, 2002Abstract Chiral separations using gas chromatography (GC) are mainly performed on chiral stationary phases (CSPs) capable of hydrogen bonding, coordination and inclusion, such as amino-acid derivatives, terpene-derived metal-coordination compounds and modified cyclodextrins, respectively.

Chiral microemulsion electrokinetic chromatography
2021Electrokinetic chromatography (EKC) has proven to be an invaluable tool for providing chiral separations. Its merits include fast, high efficiency, high resolution separations, which produce very little waste, consume minimal chemicals and are significantly more cost effective than its key competitors. EKC using chiral microemulsions (MEEKC) offers the

Multidimensional Gas Chromatography for Chiral Analysis
Critical Reviews in Analytical Chemistry, 2018Multidimensional gas chromatography (MDGC) is well-established GC method used for a diverse range of applications. Enantioselective MDGC (enantio-MDGC) has been suggested as the method of preference for the separation of extremely overlapping enantiomers.

Chiral cyclodextrin‐modified microemulsion electrokinetic chromatography
ELECTROPHORESIS, 2004AbstractCyclodextrin (CD)‐modified microemulsion electrokinetic chromatography (MEEKC) or CD‐MEEKC has not previously been applied to the area of chiral separations. Herein, the results of investigations of various microemulsions with CD additives are presented.

Adsorption models in chiral chromatography
Journal of Chromatography A, 2012The review delivers the analysis of the literature data on adsorption equilibrium in chiral systems. Chiral adsorbents usually comprise several groups of nonselective and enantioselective active sites. Each group may be heterogeneous in itself. A dynamic equilibrium between different conformations of chiral selectors, nonstoichiometric adsorption, and ...

Van't Hoff analysis in chiral chromatography
Journal of Separation Science, 2018AbstractThe present review discusses the theory and application of van't Hoff analysis in chiral chromatography, with main focus on liquid chromatography. The topics considered include the physical meaning of van't Hoff equation's parameters, interpretation of thermodynamic data in terms of retention and enantioseparation mechanisms, abnormal behavior ...

Progress of chiral countercurrent chromatography
Chinese Journal of Chromatography, 2016This article summarizes five characteristics of chiral countercurrent chromatography (CCC). The progress of chiral countercurrent chromatography is introduced. In the high speed countercurrent chromatography, the chiral selectors such as amino acid derivatives, cyclodextrin derivatives, chiral organic acid, polysaccharide and bovine serum albumin (BSA)

Chiral analysis by nano-liquid chromatography
TrAC Trends in Analytical Chemistry, 2020The concept of stereoisomerism in the biological activity of compounds in living systems emerged in 1948 with the work of Louis Pasteur, who first observed the optical activity of tartaric acid. Enantiomers can produce undesired effects on biological system, due to their different optical activity, even though they possess the same physico-chemical ...
