Reversed Phase HPLC Columns
- Sepax GP-C18
GP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. The unique mono-functional bonding chemistry of GP-C18 avoids the formation of multiple C18 layers. Such uniform stationary phase allows the separation to achieve high selectivity and high efficiency. - Sepax HP-C18
HP-C18 uses full coverage bonded silica packing, which provides exceptionally high stability. Compatible with 100% aqueous mobile phase suitable for separations of acidic, neutral and basic organic compounds, as well as pharmaceuticals, peptides, and others. - Sepax HP-C18(2)
HP-C18(2) uses a proprietary ODS bonding chemistry to a high surface area silica gel to achieve long retention time and high loading capability. The ODS density is specially designed to achieve optimal selectivity for both hydrophobic and hydrophilic compounds. - Sepax Bio-C18
The uniform stationary phase allows the separation to achieve high selectivity and high efficiency. Bio-C18 packings of 200 and 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. - Sepax BR-C18
C18 phase formed by special bonding chemistry for applications in wide range of pH (1.5-10.5). - Sepax GP-C8
GP-C8 phase is synthesized with monomeric and fully endcapped chemistry. The uniform octyl stationary phase allows high efficiency with lower hydrophobicity compared to ODS phase. GP-C8 phase is suitable for separating compounds with a wide range of hydrophobicity. It is highly recommended for separating the compounds which are too strongly retained on C18 phases. - Sepax Bio-C8
Bio-C8 phase is made of monomeric and fully endcapped chemistry. The uniform stationary phase allows the separation to achieve high selectivity and high efficiency. Bio-C8 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. - Sepax GP-C4
Monomeric and fully endcapped GP-C4 packing is bonded with butyl group that leads to moderate hydrophobicity. GP-C4 columns have the great selectivity and peak symmetry with moderate retention for separations of acidic, neutral and basic organic compounds, such as pharmaceuticals, peptides, and organic acids. - Sepax Bio-C4
Monomeric and fully endcapped GP-C4 packing is bonded with butyl group that leads to moderate hydrophobicity. Bio-C4 packings of 300 Å pore size selection are ideal for high resolution mapping of peptides and separation of natural and synthetic peptides and small proteins. - Sepax GP-Phenyl
GP-Phenyl packing materials are bonded with propyl phenyl groups that enable special interaction with ring structured compounds. The monomeric bonding chemistry gives very high efficiency and high resolution separations. GP-Phenyl phase is suitable for separations of acidic, neutral and basic organic compounds, as well as the pharmaceuticals.
