ISOLUTE® ENV+ SPE Columns, 200 mg/3 mL, 50/pk

ISOLUTE® ENV+ is a highly retentive non-polar SPE phase, for the extraction of polar analytes that are not retained by C18 or C8 sorbents.

ISOLUTE® ENV+ is a hyper crosslinked hydroxylated polystyrene-divinylbenzene copolymer, with very high surface area, ideal for extracting polar analytes from large volume water samples.

The particle size and retentive nature of the sorbent allow exceptionally high sample flow rates to be used without reducing extraction efficiency or analyte recovery.
