solution silica grade in gold extractio

Guide to Solid Phase Extraction Sigma Aldrich

Solid phase extraction (SPE) is an increasingly useful sample preparation technique. With SPE, many of the problems associated with liquid/liquid extraction can be prevented, such as incomplete phase separations, less than quantitative recoveries, use of expe nsive, breakable specialty glassware, and disposal of large quantities of organic solvents.
