Chiral separation by capillary electrochromatography with physically adsorbed stationary phase and dynamically modified stationary phase

, 2001
A novel mode of chiral separation in electrochromatogaphy (CEC) with dynamically modified stationary phase (DMS-CEC) was presented. The capillary column was packed with strong anionic exchange stationary phase, the sulfated beta -cyclodextrin (S-CD ...

PREDICTING CHROMATOGRAPHIC BEHAVIOR OF SEVERAL CHIRAL β-BLOCKERS FROM MOLECULAR STRUCTURE BY QSPR ANALYSIS

Studia Universitatis Babes-Bolyai Chemia, 2016
The chiral HPLC separation parameters of a series of fourteen β-blockers previously performed on four polysaccharide-based chiral stationary phases (CSPs) was evaluated through computational techniques, using a set of 340 molecular descriptors (MD ...

Evolutionary, Functional and Mechanistic Characterisation of Microbial Terpene Synthase‐Like Genes From Springtails

Angewandte Chemie International Edition, Volume 65, Issue 41, 5 October 2026.
A genome analysis revealed the presence of many bacterial‐type terpene synthases in springtails. Four enzymes from Sinella curviseta were functionally characterised, resulting in the isolation of several compounds including sinellene ether, the first diterpene ether identified from a terpene synthase that represents a novel skeleton.

Simultaneously molecular imprinting chiral stationary phase

, 2000
Molecular imprinting chiral stationary phases against amino acid derivatives were preparted by utilizing two template molecules simultaneously and evaluated in high performance liquid chromatographic mode. It was found that when both of the two molecular

CHIRAL RECOGNITION OF ENANTIOMERIC AMIDES ON A DIAMIDE CHIRAL STATIONARY PHASE BY GAS-CHROMATOGRAPHY

, 1993
Several alpha-alkyl-, alpha-cycloalkyl- and alpha-aromatic-substituted ethylamine enantiomers were separated with a cross-linked polycyanoethyl vinyl siloxane-L-valine-tert.-butylamide fused-silica capillary column.
