Description of HPLC Column
For normal-phase chromatography, ourproduct line offers new Diol bonded silica packing materials. Diol may also be used as a polar sorbent in normal phase. Like bare silica, Diol has the ability to form hydrogen bonds and has the capacity to separate structure isomers. Since most of its surface is covered with organic functions, the Diol absorbs less water, which leads to a more reproducible activity. It is also the sorbent of choice when working in normal phase in the presence of water. It has a different selectivity than bare silica gel, and slight modification in the composition of solvent mixture may be necessary to obtain a similar retention.
The Diol column is more stable than the traditional normal phase columns, such as NH2, SiO2. Compared with NH2/SiO2 column, the Diol column is not sensitive with water. The Diol column could also be used in reverse phase analysis.
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).
