Fractionation of plant extracts by supercritical fluid extraction and direct introduction in capillary gas chromatography using a programmable temperature vaporizer

, 1999
A simple procedure to improve the sensitivity achievable in the analysis of supercritical fluid extracts of complex matrices is proposed. The method involves the offline coupling of supercritical fluid extraction and gas chromatography (GC) in such a way

Robust and Thermally Stable Silicone Aerogels with Hyperconnected Network via Kinetically Optimized Hyperbranched Silane Precursors

Advanced Science, Volume 13, Issue 34, 19 June 2026.
Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.

A New Kinetic‐Mechanistic Approach Towards Spectrophotometric Bioanalysis of 2‐Phenylethylamine as a Sympathomimetic Agent Using Sodium Isopropyl Xanthate

Analytical Science Advances, Volume 7, Issue 1, June 2026.
ABSTRACT 2‐Phenylethylamine (2‐PEA), an aromatic biogenic amine, demonstrates significant physiological and toxicological effects on human health. A variety of conventional methods have been widely used for the determination of 2‐PEA. However, the necessity of complex sample preparation and high cost of instrumentation may pose challenges to their ...

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, Volume 103, Issue 6, Page 623-632, June 2026.
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.
