ISOLUTE® HAX is a mixed-mode sorbent providing clean extracts for acidic compounds from complex biological fluid samples using a dual retention mechanism.

ISOLUTE® HAX combines non-polar (C8) and strong anion exchange retention  (-NR3+mechanisms to isolate acidic analytes from complex aqueous matrices such as urine and plasma.

Analytes are initially retained by a non-polar retention mechanism, with inorganic salts, polar interferences such as phospholipids and large molecular weight peptides and proteins passing directly through the sorbent bed.  The pH is then adjusted to allow an ion exchange retention mechanism to retain the analyte(s).  Non-polar interferences are removed using an organic solvent or organic solvent/water wash.  Analytes are then eluted in an extra clean fraction.

ISOLUTE HAX is available in a wide range of SPE columns and 96-well plate formats.
