Biotage has added to its range of sample preparation products with Evolute Wax, a mixed-mode weak anion exchanger developed for the extraction of strongly acidic analytes from aqueous samples.
The resin-based sorbent is surface modified with well-defined hydroxyl-functional oligomers.
An optimised combination of non-polar (hydrophobic), polar (hydrophilic) and anion exchange interactions allows efficient extraction of strongly acidic analytes of wide-ranging polarities.
Such strongly acidic analytes are typical of organophosphate pesticide metabolites and Evolute Wax provides analytical scientists with the ability to extract such compounds more efficiently from diverse matrices, ranging from ground water to blood.
The non-polar/anion exchange dual-retention mechanism allows the use of a rigorous interference regime, providing clean extracts and reducing matrix effects associated with LC-MS/MS analysis.
