GPC HFIP-805 300x8mm GPC HFIP solvent

The Shodex GPC HFIP-805 GPC column 300x8.0mm, 10µm, contains a porous styrene-divinylbenzene gel with a nominal pore size of 5,000 Å. With hexafluoroisopropanol (HFIP) as the exclusively intended mobile phase, Shodex GPC HFIP-805 covers a typical molecular weight range determined with PMMA standards of approx. 20,000 to 600,000 Da. The wide-pore packing extends the fractionation range to larger chains of hydrogen-bonding 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-805 are high-molecular-weight polyamides, polyesters and technical condensation 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.
