C18 Columns / HPLC

NEW - Inertsil Continues to Evolve to InertSustain. Generally, silica based C18 columns are mechanically stable & provide high efficiencies, however, they cannot be used under alkaline conditions & their residual silanol groups tend to adsorb organic bases. InertSustain C18 columns employ a radically new type of silica, in which the surface of the silica is uniquely modified, enabling precise control of the silica properties. InertSustain C18 columns inherit the advantages of all the current Inertsil HPLC C18 columns (e.g., extremely low operating back pressure, superior inertness to typically any analytes, high efficiency and compatibility with a wide range of solvents), but now can be used for wide pH analysis with consistent performance from column to column and lot to lot.

Inertsil ODS-EP contains a polar functional group embedded between the silica surface and the C18 group. The embedded polar group makes the C18 phase stable in 100 % aqueous eluents without "phase collapse." This phase is also extremely "base deactivated" and provides superior peak shape for acids and bases in organic eluents as well a...
