Supercritical Fluid Extraction of Lipids
Researchers at the Virginia Tech (Blacksburg, Virginia) Department of Chemistry have used supercritical fluid extraction with methanol-modified carbon dioxide to separate polar lipid fractions from crude soybean lecithin.
Researchers at the Virginia Tech (Blacksburg, Virginia) Department of Chemistry have used supercritical fluid extraction with methanol-modified carbon dioxide to separate polar lipid fractions from crude soybean lecithin. Pure carbon dioxide was used to remove the neutral lipids. The phosphatidyl choline-enriched fraction of the soybean lecithin was the target of this extraction. They isolated and identified six components in the crude soybean lecithin extract.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
Reflecting on the Influence of the Current State of Sample Preparation on GC, Part 2: Techniques
May 9th 2024In this installment, we examine trends in the use of sample preparation techniques through the lens of instrumental analysis by gas chromatography (GC) and GC–mass spectrometry (GC–MS).
