Sorbentien helfen dabei, Bestandteile eines Gemisches in den verschiedenen Chromatographie-Methoden zu trennen. Gebrauchsfertige Chromatographie-Sorbentien beschleunigen und vereinfachen jegliche Verfahren zur Isolierung, Identifizierung oder Reinigung. Sorbentien, die als stationäre Phase verwendet werden, werden für präzise Ergebnisse passend zu den chemischen und physikalischen Eigenschaften der Probenbestandteile in unterschiedlichen Partikelgrößen oder Polaritäten angeboten. Chromatographie-Sorbentien sind mit oder ohne Zusätze wie Bindemittel zur Stabilisierung oder Fluoreszenzindikatoren, um Flecken unter UV-Strahlung sichtbar zu machen, erhältlich.
