Phenogel GPC/SEC Columns

Phenogel is a range of Phenomenex columns for non-aqueous gel permeation chromatography (GPC/SEC), designed for high-performance analysis of polymers, oligomers, and other macromolecules based on molecular weight.

Phenogel columns are based on a highly cross-linked styrene-divinylbenzene (SDVB) packing material. Precise control of pore size, pore size distribution, total pore volume, particle size, and degree of cross-linking during manufacturing provides high resolution, mechanical and chemical stability, and excellent column-to-column reproducibility.

Key Benefits of Phenogel

• High resolution — precisely controlled pore structure provides high separation efficiency and tight calibration curves.
• Excellent reproducibility — controlled packing characteristics ensure consistent performance from column to column.
• Long column lifetime — highly cross-linked SDVB provides excellent mechanical and chemical stability.
• Wide molecular weight range — available pore sizes range from 50 Å to 10⁶ Å, along with a Linear(2) configuration for broad molecular weight analysis.
• Optimized pore size selection — columns are available for applications ranging from low-molecular-weight organic compounds to polymers with molecular weights up to 10,000,000 Da.
• Broad organic solvent compatibility — Phenogel columns are compatible with THF, DMF, DMSO, HFIP, chloroform, toluene, methylene chloride, and other organic mobile phases.
• High temperature stability — stable up to 140 °C, enabling analysis of polymers with limited solubility and the use of viscous solvents such as DMF and DMSO.
• High efficiency — for 300 × 7.8 mm columns, minimum efficiency is 45,000 plates/m for 5 µm particles and 35,000 plates/m for 10 µm particles.
