Linear Type GPC Column (LF)

These GPC columns filled with porous gel having a broad pore size distribution exhibit high calibration curve linearity. These columns eliminate shoulders in chromatograms as seen with mix columns filled with a mixture of several gels. Various solvents can be used for solvent replacement. Three sizes are available: standard columns, downsized columns for rapid analysis, and semi-micro columns.
