CHM® CHROMPACK SPE columns

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. According to the principle of “like dissolves like”, SPE can be classified in four types: inverse SPE, normal phase SPE, ion exchange SPE, absorption SPE.
CHM® ChromPACK offer silica-based, organic copolymer or inorganic chemical based SPE columns. The filling material of ChromPACK columns includes C18, C18-ne, C8, NH2, CN, GCB, Alumina, Florisil, Silica, SAX, SCX, PSA, PRS PLS, PCX, PAX. Column capacities consist of 1, 3, 6, and 12 ml sizes. Our manufacturing process minimizes variability and improves recovery and cleanup procedures.
