Factory supply 5µm 120A Polar-RP HPLC Column

Description of  Polar RP HPLC Column
Traditional polar embedded reversed phase column use amino acid amide group bonding on the surface of the silica, which may cause residual amino. The residual amino presents alkaline characteristics, when analysis the acid (such as organic acid), will cause the peak tailing. Starlabadopts unique bonding process, solves the problem of residue amino, and at the same time adopts double end-capped technology to get excellent symmetrical peak shape.

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. Different selectivity from traditional reverse phase such as C18 and C8, especially for the analysis of polar compounds
2. Exhibit at 100% water contents in the mobile phase, even better than the C18-Aqueous
3. Excellent peak shape for the analysis of polar and basic compounds,particularly at mid pH, due to the“shield” effect of polar linkage to silanol activity by forming hydrogen bonding

Applications of HPLC Column
1, Separation of Organic Acid
2, Ephedra
