Pre-packed columns, cartridges, and guard columns for separation of biomolecules and organic/inorganic analytes; includes normal/reversed phase HPLC, UHPLC, LC-MS, HILIC, mixed-mode, ion exchange, ligand exchange, and affinity column formats.
This Cogent RP C18™ Stationary Phase has been a premium value and used by HPLC laboratories for many years. It is double end capped ( fully ), with traditional bonding of an 18 carbon silane to the highest purity silica available, making this column ideal as an Alternate in USP Methods that use the L1 Classification.With a 5 µm Particle, this column works well with higher flow rates and lower back pressures compared with smaller particles. Used for hydrophobic or neutral compounds in Reversed Phase, this Octadecyl Phase is excellent for long chain fatty acids. Expect longer retention than with a C8 column. This size column is often used when shorter run times are needed but 50mm long columns do not provide enough resolution.

This Cogent RP C18™ Wide Pore Stationary Phase has been a premium value and used by HPLC laboratories for many years. It is double end capped ( fully ), with traditional bonding of an 18 carbon silane to the highest purity silica available. This makes this column ideal as an Alternate in USP Methods that use the L1 Classification, for large molecules.With a 10 µm Particle and 300A Pore Size, this column works well with higher flow rates and lower back pressures. Used for large hydrophobic or neutral compounds in Reversed Phase, this Octadecyl Phase is also excellent for long chain fatty acids.

Utilizing proprietary surface technologies, SRT-10 and SRT-10C SEC phases are made of uniform, hydrophilic, and neutral nanometer thick films chemically bonded on high purity and mechanically stabilized 10 µm silica. The well-controlled surface chemistry results in excellent lot-to-lot reproducibility. Our unique bonding chemistry, coupled with the maximized bonding density, allows SRT-10 and SRT-10C SEC phases to provide high stability and negligible non-specific interactions. SRT-10 and SRT-10C packings have large pore volume, resulting in high separation resolution. Typical applications for SRT-10 and SRT-10C columns include separation and detection of biological molecules and water-soluble polymers in aqueous buffers.
