Supercritical Fluid Chromatography Waters
WebTo ensure compatibility of sample solvent composition between SFC and LC, 10 μL of water was added to all samples between SFC and LC analysis. Water is not compatible with the stationary phase of the chiral column used in the SFC separation but is fundamental to ensure a Gaussian peak shape for the more polar compounds in the RPLC separation. WebAvoid racemic mixtures by using chirally pure starting materials (synthons), asymmetric synthesis, chemical catalysis or biocatalysis. (2) Post-synthetically using chromatography. Chiral stationary phases (HPLC and SFC) can separate racemic mixtures into the individual isomers and can be scaled-up to preparative sizes. WebJan 20, 2024 · Herein, we report on the synthesis and high-performance liquid chromatography (HPLC) resolution of a new atropisomeric C2-symmetry chiral monomer based on the 3,3′-bithiophene core, which was developed to produce novel, inherently oligomeric chiral electroactive materials. The analytical enantioseparation was optimized … includegraphics margin
