Oasis Sorbent Selection Plate

The Oasis sorbent selection plate is specifically designed to take the guesswork out of SPE method development. The 96-well plate format conveniently contains 3 rows each of the four Oasis mixed-mode, ion-exchange chemistries: strong and weak anion exchangers (MAX and WAX) and strong and weak cation exchangers (MCX and WCX). Having all Oasis ion-exchange sorbents in a single plate is convenient for scouting the best ways to accomplish efficient isolation of unknown analytes, zwitterionic compounds, or mixtures of analytes with different retention/elution properties. Sample preparation method development can be quickly and easily achieved with the use of only two SPE protocols on these four chemistries.
