Inertness and durability combined in a new HPLC column

GL Sciences newly developed technologies has enabled the modification of pore size, and its homogeneity, along with the amount of silanol groups of the base silica to be adequately controlled for each ligand in a variety of phases and applications.

This evolved surface silica (ES Silica) allows GL Sciences InertSustain™ Series to have a wide portfolio with extremely inert, chemical sustainability and batch to batch reproducibility for state-of-the-art analysis.


While other columns show poor peak shape, insufficient separation efficiency often with secondary interactions, and unsuitable physical properties of base silica that result in poor reproducibility. 

InertSustain™ Series delivers symmetric peaks with high efficiency.



Superior inertness to typically any analytes



High efficiency & compatibility with a wide range of solvents



Extremely low operating back pressure
