Evaluation of carbon nanotubes as chiral selectors for continuous-flow enantiomeric separation of carvedilol with fluorescent detection

Autor: Liliana Patricia Fernandez, María Carolina Talio, Marta Olga Luconi, Raúl Alejandro Silva

Publikováno v: Journal of Pharmaceutical and Biomedical Analysis. 70:631-635

Single-walled carbon nanotubes (SWNT) are proposed as chiral selectors for separation of carvedilol stereoisomers beginning since its racemic mixture. The novel developed FIA-methodology employs a microcolumn (mC) packed with a few milligrams of SWNT
