Generally, silica based columns are mechanically stable and provide high efficiencies, however, they cannot be used under alkaline conditions and their residual silanol groups tend to adsorb organic bases. InertSustain employs a radically new type of silica, in which the surface of the silica is uniquely modified, enabling precise control of the silica properties. InertSustain inherits the advantages of all the current Inertsil HPLC 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.
The InertSustain Serie has the following columns available; InertSustain C18, InertSustain AQ-C18, InertSustainSwift C18, InertSustainSwift C8, InertSustain Phenyl, InertSustain Phenylhexyl, InertSustain Cyano, InertSustain NH2, InertSustain Amide, InertSustainBio C18.
