Advances in supercritical fluid chromatography [PDF]
Analytical 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

Lipidomics by Supercritical Fluid Chromatography [PDF]
International Journal of Molecular Sciences, 2015 This review enlightens the role of supercritical fluid chromatography (SFC) in the field of lipid analysis. SFC has been popular in the late 1980s and 1990s before almost disappearing due to the commercial success of liquid chromatography (LC). It is only 20 years later that a regain of interest appeared when new commercial instruments were introduced.

Progress in the Enantioseparation of β-Blockers by Chromatographic Methods
Molecules, 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.,

Supercritical fluid chromatography for vitamin and carotenoid analysis: an update covering 2011-2021
Journal of Chromatography Open, 2022 As it is known, the chromatographic separations of vitamins is not a trivial issue. The subtle heterogeneity among homologs belonging to the same group makes it difficult to perform their speciation.
