Chiral Recognition for Chromatography and Membrane-Based Separations: Recent Developments and Future Prospects

Molecules, 2021
With the rapid development of global industry and increasingly frequent product circulation, the separation and detection of chiral drugs/pesticides are becoming increasingly important. The chiral nature of substances can result in harm to the human body,

Cannabis through the looking glass: chemo- and enantio-selective separation of phytocannabinoids by enantioselective ultra high performance supercritical fluid chromatography [PDF]

, 2017
By using the Inverted Chirality Columns Approach (ICCA) we have developed an enantioselective UHPSFC method to determine the enantiomeric excess (ee) of (-)-Δ(9)-THC in medicinal marijuana (Bedrocan®).

Chiral separation by SMB chromatography [PDF]

Separation and Purification Technology, 2000
The paper deals with chiral separation by simulated moving bed (SMB) chromatography. A model for the prediction of the cyclic steady-state performance of the SMB, based on the analogy with the true moving bed (TMB), is developed assuming multicomponent adsorption equilibria, axial dispersion flow and the linear driving force approximation to describe ...

Development and validation of a sensitive and robust chiral method for (R)-propylene oxide: From chiral gas chromatography to chiral liquid chromatography with pre-column derivatization

Journal of Chromatography Open
Propylene oxide (PO) is an important chemical commodity and a chiral building block to prepare pharmaceutical compounds. It is crucial to develop a sensitive and robust chiral method that can be used to assess the enantiomeric purity of PO and safeguard ...

Polysaccharide Derivatives as Unique Chiral Selectors for Enantioselective Chromatography

CHIMIA, 2017
From the beginning of the 1980s, the life science industry increasingly recognized the importance of chirality in biological interaction processes, but the methods for preparing optically pure drugs were still limited.

Enantioseparation of syn- and anti-3,5-Disubstituted Hydantoins by HPLC and SFC on Immobilized Polysaccharides-Based Chiral Stationary Phases

Separations, 2022
The enantioseparation of syn- and anti-3,5-disubstituted hydantoins 5a–i was investigated on three immobilized polysaccharide-based columns (CHIRAL ART Amylose-SA, CHIRAL ART Cellulose-SB, CHIRAL ART Cellulose-SC) by high performance liquid ...

Chiral molecule adsorption on helical polymers [PDF]

, 2003
We present a lattice model for helicity induction on an optically inactive polymer due to the adsorption of exogenous chiral amine molecules. The system is mapped onto a one-dimensional Ising model characterized by an on-site polymer helicity variable ...
