HPLC silica columns, Viva Silica (USP L3)
Supplier: Restek
These Viva columns are based on a wide pore material designed for optimal large-molecule separations. Base-deactivated spherical silica is useful for normal-phase or HILIC separations. These columns have a narrow distribution around the mean pore size, permitting a larger portion of the silica surface to play a role in the separation.

Doppelte Vespel®-Ringeinlassdichtungen
Supplier: Restek
Eine Ringeinlassdichtung verbessert die Leistung der Injektionsöffnung erheblich, da sie auch nach wiederholten Temperaturzyklen dicht bleibt, ohne dass die Reduziermutter erneut festgezogen werden muss. Diese Dichtung verfügt über zwei weiche Vespel®-Ringe, von denen einer in die Oberseite und der andere in die Unterseite eingebettet ist. Diese Ringe machen eine Unterlegscheibe überflüssig und sorgen dafür, dass nur ein sehr geringes Drehmoment erforderlich ist, um eine leckdichte Abdichtung herzustellen.

Preparative HPLC columns, Ultra IBD
Supplier: Restek
Ultra IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today. It is compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.

Preparative HPLC columns, Ultra Biphenyl
Supplier: Restek
These biphenyl columns offer a greater degree of dispersion than conventional phenyls and a greater degree of polarizability than phenyl hexyls, creating higher selectivity and a greater range of usability. Because of these heightened interactions, this column shows substantial increases in retention—especially for dipolar, unsaturated, or conjugated solutes—and enhanced orthogonal selectivity when using methanol mobile phases.
