InertSustain C18
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 C18 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 C18 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.
BENEFITS
Inert : Superior Peak Shape with Better Resolution
Sustain : Wide pH Analysis with Endurance at High pH
C18 : Strong Retentivity, Low Operating Pressure
Introducing a Radically New Type of Silica
Radically New Silica Gel
It was not possible to end-cap 100% of residual silanols using traditional chemical modification procedures.
GL Sciences studied the possibility of developing a radically new type of silica, a silica that would provide both high intertness (base deactivation) and durability at a wide range of pH.
Our focused R&D effort lead to the development of “Evolved Surface Silica”, in which adsorption sites and
silanol distribution are strictly controlled. This process enables delivery of an HPLC column with the most advanced combination of base deactivation and chemical compatibility.
The introduction of Evolved Surface Silica and our cutting-edge chemical bonding technology make InertSustain
C18 compatible with100 % aqueous mobile phases, while maintaining strong non-polar retentivity. InertSustain
C18 offers superb separation power with unmatched inertness to virtually any type of analyte.
