Clear, practical coverage of an important reemerging technology supercritical fluid extraction provides a clear, practical, step-by-step introduction to a sample preparation method that helps laboratories reduce or eliminate the use of halogenated solvents, extract samples more quickly and efficiently, and improve the accuracy of their results.
Supercritical fluid extraction is the process of separating one component from another using supercritical fluids as the extracting solvent. Extraction is usually from a solid matrix, but can also be from liquids. Sfe can be used as a sample preparation step for analytical purposes, or on a larger scale to either strip unwanted material from a product or collect a desired product. These essential oils can include limonene and other straight solvents.
