Description of Phenyl HPLC Columns
The Phenyl HPLC column is based on ultra-pure silica gel, bonded to the propyl phenyl group on the surface of the silica gel, and processed through a thorough double-end bonding process. The column has high surface coverage and excellent separation of aromatic compounds, polar compounds, and difficult-to-separate drugs.
Compared to a reversed-phase column in which a linear alkane is bonded, the phenyl column has a different selectivity, or can be said to be a complementary selectivity, and is particularly suitable for the separation of a compound having an aromatic ring.
Ultra-pure, fully porous spherical silica gel with a purity of >99.999%. It uses a unique silica gel matrix treatment technology to make the pore size more uniform. Unique stationary phase bonding and double tailing technology make the peak shape symmetry better; lower UV and MS Loss; has a high surface coverage and increases the chemical stability of the bonded phase.
Phenyl HPLC Columns Characteristics
Different from the linear alkane chain;
Excellent separation selectivity for aromatic compounds and polar compounds;
Can replace most of the phenylpropyl bonded silica column for HPLC on the market.
