Solid Phase Extraction (SPE) is a technique widely used for sample preparation and purification or isolation. Over the last twenty years, the popularity of this technique has increased dramatically. SPE extends the lifetime of chromatographic systems and improves qualitative analysis. SPE is mainly used to extract an analyte (compound of interest) from impurities in a wide variety of matrices like biological fluids (plasma, blood and urine), water, soil, etc., to concentrate analyte of interest, or purify samples prior to the analysis.
Common SPE applications:
·Pesticides and antibiotics in food and agricultural matrices
·Pharmaceutical s and metabolites in biological fluids
·Drugs of abuse in biological fluids
·Vitamins and proteins or peptide
·Organic compounds in water and environment
CNW offers two series of CNWBOND and Poly-Sery SPE products to our customers.
CNWBOND series mainly includes the silica-bond and adsorption SPE cartridges. These products are used most widely in SPE processing. CNWBOND uses very pure and reproducible bulks to make your samples to be very clean and ready to be analyzed in the next step. The phases includes C1, C2-ne, C4, C4-ne, C8, C8-ne, C12, HC-C18, LC-C18, C18-ne, CYH(Cyclohexyl), PHE(Phenyl), Silica, CN (Cyano), Diol, NH2, NH2-ne, WAX, PSA, SAX, WCX, PRS, SCX, C8/SCX, C8/SAX, Florsil, Alumina-A, Alumina-N, Alumina-B, Celite545, Coconut Charcoal, Carbon-GCB, GCB/NH2, GCB/PSA, SAX/PSA, GCB/SAX/PSA, GCB/SAX, GCB/NH2/Si etc.
Poly-Sery series is the polymer-based SPE cartridge, which includes different modified copolymer types. These products are becoming more and more popular used in modern SPE processing, because these sorbents have special properties of faster throughput, higher reproducibility, stronger retention and selectivity, more stable pH durability etc., which make your method to be easy and faster with satisfied result. The phases includes MCX, PSD, XAD2 etc.
