bond elut™ plexa™ pcx is a new addition to the plexa family
and uses a mixed mode polymer cation exchange technique.
this advanced spe sorbent retains neutral and acidic
compounds from biofl uids via hydr-ophobic interactions and
concentrates basic analytes due to ion-exchange capabilities.
a single method is suffi cient to fractionate different classes
of compounds at high recoveries in clean extracts. acidic and
neutral compounds are eluted in a neutral fraction, while
basic compounds elute in a basic fraction.
