InertSustain® NH2

InertSustain® NH2

Highly durable Amino column

Available in reversed phase mode and normal phase mode


InertSustain Series

GL Sciences developed new Silica gel “Evolved Surface Silica” for InertSustain Series which provides both high inertness and high durability. Inert-and-sustainable InertSustain series HPLC columns are the latest models of GL Sciences and are recommended as the first choice for various purpose.


InertSustain NH2 has aminopropyl groups bonded to newly developed Silica gel.

Generally, aminopropyl columns are used for simultaneous analysis of sugars or vitamin E when other reversed phase columns are unable to achieve separation, though occasionally bothered with inconsistent retention times. GL Sciences has improved that weak point and now presents InertSustain NH2 as a highly stable and reliable amino column.  


Inertsil NH2 is another Phenylpropyl bonded column from GL Sciences. By employing the new Silica gel, InertSustain NH2 is more durable than Inertsil NH2.
