Solid-Phase Extraction (SPE) is a separation process by which compounds that are dissolved or suspended in a liquid mixture are separated from other compounds in the mixture according to their physical and chemical properties. Analytical laboratories use solid-phase extraction to concentrate and purify samples for analysis. Solid-phase extraction can be used to isolate analytics of interest from a wide variety of matrices, including urine, blood, water, beverages, soil and animal tissue. SPE is solvent consumption, convenient, safe and high efficiency. Our manufacturing process minimizes variability and improves recovery and clean-up procedures.
