ISOLUTE® ENV+ on-line SPE cartridges

ISOLUTE® ENV+ has long been the sorbent of choice of solid phase extraction of polar organics from water samples, and is now available in on-line cartridge format.

ISOLUTE ENV+ is a high purity, hyper cross-linked polystyrene based polymeric sorbent with a hydroxylated surface, capable of extracting a wide range of polar, water soluble analytes from aqueous samples. Its high surface area and optimized pore structure make it ideal for extraction of very polar analytes, such as phenols and acid herbicides. It has a very high capacity for polar compounds (up to 50% by weight for caffeine) reducing analyte breakthrough and improving recovery for even the most polar of compounds. ISOLUTE ENV+ is totally water wettable, so it will never become de-conditioned, even if it runs dry. Columns do not need to be stored in solvent after use. Biotage ISOLUTE ENV+ On-line Cartridges combine these unique sorbent characteristics with the convenience of fully automated SPE.
