Beschreibung: Native silica is generally regarded as the most polar SPE sorbent available. Bond Elut™ SI is particularly effective at separating compounds with a very similar structure. Applying the analytes in a non-polar solvent, then increasing the solvent polarity by increasing the concentration of a polar modifier, such as THF or ethyl acetate, delivers effective separations.

Beschreibung: Bond Elut™ SAX ist ein starker Anionenaustauscher-Sorbens, der sich ideal für die Extraktion von Verbindungen wie Carbonsäuren eignet, die auf schwachen Anionenaustauscher-Sorbentien möglicherweise nicht effektiv zurückgehalten werden. Das Sorbens wird in Form eines Chlorid-Gegenions geliefert. Sie können die Selektivität der Phase ändern, indem Sie das Chloridion durch andere Anionen wie Acetat und Hydroxid ersetzen.

Beschreibung: Bond Elut™ C8 is very similar in properties to C18, but is not as retentive for non-polar compounds, due to its shorter hydrocarbon chain, and therefore reduced carbon loading. C8 is an excellent replacement for C18 when analytes are too strongly retained for effective elution. The potential for polar interactions is somewhat higher than for C18 because there is less coverage of the silica surface. These polar interactions are not, however, a significant property of C8.
