Advances in supercritical fluid chromatography [PDF]

open access: yesAnalytical Science Advances, 2021
More than a century ago researchers recognized the unique properties that inorganic gases have above their critical point. Since then, different gases and liquids have been investigated. It was Ernst Klesper who reported on the very first chromatographic separations that used a supercritical fluid as the mobile phase back in 1962. In a brief report, he

Progress in the Enantioseparation of β-Blockers by Chromatographic Methods

open access: yesMolecules, 2021
β-adrenergic antagonists (β-blockers) with at least one chiral center are an exceedingly important class of drugs used mostly to treat cardiovascular diseases. At least 70 β-blockers have been investigated in history. However, only a few β-blockers, e.g.,
