The way to ultrafast, high-throughput enantioseparations of bioactive compounds in liquid and supercritical fluid chromatography [PDF]

, 2018
Until less than 10 years ago, chiral separations were carried out with columns packed with 5 or 3 μm fully porous particles (FPPs). Times to resolve enantiomeric mixtures were easily larger than 30 min, or so.

Quantitative Capillary Supercritical Fluid Chromatography and Supercritical Fluid Extraction of Basic Drugs of Abuse

CHIMIA, 1992
Capillary SFC of basic drugs of abuse have been studied using two different columns, and the results were compared with GC. These results have proved the ability of supercritical CO2 to solubilize and extract basic drugs of interest.

Supercritical Fluid Chromatography

International Journal of Advanced Research in Science, Communication and Technology, 2023
History of Supercritical Fluid Chromatography In 1822, the French physicist Charles Cannard de La Tour placed a liquid and a flint ball in a Papin rifle pressure vessel and heated the liquid with a sealed cannon. 1) When the container was shaken, the bullet broke through the air-liquid interface, and the sound of the bullet scattering was heard.

Discrimination of Lipid Hydroperoxide Positional Isomers Using SFC–MS/MS With Sodium Ion: Its Application to Evaluating the Oxidation Mechanisms of Oxidized Oils

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Advanced lipid profiling relies on liquid chromatography–tandem mass spectrometry (LC–MS/MS), but long analysis times remain a challenge. Supercritical fluid chromatography (SFC)–MS/MS using supercritical carbon dioxide offers a faster and more environmentally friendly alternative.

PEG Alternatives in Liposomal Nanocarriers: Physicochemical Characteristics and Sustainable Process Strategies

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The global trend toward sustainable and intensified bioprocesses is driving innovation in the design and scalable synthesis of liposomal nanocarriers, a cornerstone of modern drug delivery. For decades, these nanosystems have relied exclusively on polyethylene glycol (PEG) for their sustained circulation in vivo, but they are currently ...
