GPC K-2006M, 20.0 x 300 mm, preparative HPLC column

The Shodex GPC K-2006M preparative GPC column 300x20mm, 10µm, contains a porous, spherical styrene-divinylbenzene gel with a nominal pore size of 10,000 Å as a mixed-pore gel. The packing material consists of coarser polymer particles designed for preparative operation. With chloroform or, after approved solvent exchange, the respective solvent as the primary mobile phase, Shodex GPC K-2006M covers a typical molecular weight range determined with polystyrene standards of approx. 1,000 to 20,000,000 Da. The chloroform-packed preparative variant 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 K-2006M are preparative fractionation of broadly distributed 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.
