Available for sugar analysis in reversed phase mode
Many Amino columns on the market are modified with Secondary or Tertiary Amines in order to improve column durability. However, that leads to the adsorption of reducing sugars and anomer resolution when analysing sugars.
Inertsil NH2 is modified with Primary Amines and is able to separate sugars without adsorption and anomer resolution.

Unique selectivity in normal phase mode
Inertsil NH2 achieves better separation than other commercially available Amino columns as it is modified with Primary Amines.
The figure below shows that Inertsil NH2 is able to separate isomers of Tocopherol with good peak shape in short time compared to other Amino columns on the market.
Primary Amines on the surface provides Inertsil NH2 unique selectivity as a normal phase column. Inertsil NH2 retains acidic compounds strongly and basic compound weakly.
