Description of HPLC Column
NH2 columns are used in normal phase LC analysis mostly.

Advantage of HPLC Column
Unique bonding and end-capping techniques
High purity bare silica packed in clean room
Average sample size &pore size make well flow rate
Perfect peak shape&high peak volume
Excellent separation efficiency, stability and reproducibility
Wide PH application range for different components extraction
Excellent peak shape, most especially for polar, acidic and basic compounds.
High column efficiency of Consistency and uniform
Lasting and sound column lifetime 
Wide Application :Pharmaceutical, food safety, pesticide, inspection and quarantine and industry etc.
Series of packing sorbent for wide selectivity.
Proprietary surface modification for smooth and inert silica surface.
Can be used with most hplc instruments (Agilent ,Biotage,Grace  etc).

Features of HPLC Column
1. Propyl-amino silane phase bonded to Silica
2. Used for normal phase and weak anion-exchange, and for reversed-phase HPLC of polar compounds
3. for applications in aggressive normal phase mode with aqueous eluent
4. Vitamins A and D are separated in the normal-phase mode
5. Carbohydrates and monosaccharide can be separated in the reversed-phase mode on NH2, but not suit for the separation of compounds and sugars that contain aldehyde, carbonyl
6. In the low pH buffer solution, can separate some negatively charged molecules for weak anion exchange mechanism

Applications of HPLC Column
1. Acarbose
2. Fructose, Glucose, Maltose, Maltotriose and Maltotetraose
3. Xylose, Saccharose and Lactose
4. Matrine
