GPC H-2002.5, 20.0 x 500 mm, preparative HPLC column

The Shodex GPC H-2002.5 preparative GPC column 500x20mm, 15µm, consists of a porous, spherical styrene-divinylbenzene gel with a nominal pore size of 300 Å. The packing material comprises coarser polymer particles designed for preparative operation. With chloroform, or after authorised solvent switching, as the primary mobile phase, the Shodex GPC H-2002.5 covers a typical molecular weight range of approx. 300 to 8,000 Da as determined with polystyrene standards. The long custom 20 mm ID format transfers the corresponding analytical pore selectivity to higher sample loads. The larger column ID supports higher sample loads and the transfer of analytical GPC separations to the preparative scale. Typical applications of Shodex GPC H-2002.5 are preparative fractionation of oligomers and low-molecular-weight polymers; the practically usable range depends on polymer structure, eluent and calibration.

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.
