GPC HFIP-803 300x8mm GPC HFIP solvent

The Shodex GPC HFIP-803 GPC column 300x8.0mm, 10µm, contains a porous styrene-divinylbenzene gel with a nominal pore size of 500 Å. With hexafluoroisopropanol (HFIP) as the exclusively intended mobile phase, Shodex GPC HFIP-803 covers a typical molecular weight range determined with PMMA standards of approx. 1,000 to 30,000 Da. The small pore fraction focuses HFIP-GPC on oligomers and low-molecular-weight polymers. Size separation occurs via the pore volume accessible in the polymer gel; HFIP also keeps many strongly hydrogen-bonding polymers in solution. Typical applications of Shodex GPC HFIP-803 are polyamide oligomers, polyesters, resin components and low-molecular-weight fluorinated-alcohol-soluble polymers; salt additives and operating conditions must be adapted to the polymer and method.

Features and Benefits

• Styrene-divinylbenzene polymers for organic GPC
• Series for THF, DMF, and other solvents
• Single and mixed pore distributions
• Rapid, semi-micro, and preparative formats
• Molecular weight ranges from oligomers to ultra-high-molecular-weight polymers

Additional Information

The Shodex GPC product family is based on porous, spherical styrene-divinylbenzene gels. Defined single-pore, linearized multi-pore materials, and mixed gels cover a wide range of molecular weight distributions. The KF series is primarily intended for THF, while the KD series is designed for DMF and polar organic eluents. HK, LF, and HQ columns are designed for fast or highly efficient analyses. Preparative K, KF, and H formats transfer pore selectivity to higher loadings. Molecular weight ranges always depend on the polymer structure, solvent, and calibration standard.
