Asahipak GF-HQ series are polyvinyl alcohol-based material. Designed for both aqueous and organic solvent systems.

Supplier: TOSOH Bioscience

These standards consists of bulk quantities of polystyrene and polyethylene oxide standards of varying molar mass and pre-mixed quantities of polystyrene polymers for calibration of GPC columns.

Supplier: Resonac

PROTEIN KW-800 and KW400 series HPLC columns are specifically designed for protein analysis by aqueous size exclusion chromatography (GFC). PROTEIN LW-803 and LW-403 4D are designed for antibody analysis. They are packed with porous silica particles coated with a hydrophilic copolymer. They fulfill USP L20, L33, and L59 requirements.

Supplier: Resonac

Columns for simultaneous analysis of saccharides and organic acids.

Supplier: Resonac

The GF-HQ series are designed for aqueous (GFC) and organic (GPC) size exclusion chromatography. High performance analysis of samples containing hydrophilic and hydrophobic parts, such as surfactants is possible.

Supplier: VARIAN

Polystyrene standards for many organic solvents either for conventional GPC column calibration or for calibrating light scattering and viscosity detectors that provide equidistant calibration points for greater accuracy.

Supplier: Resonac

Size Exclusion Standard, Standard SH-75, 0,5 g × 7 standards, with MW range 590000 - 7500000, PS

Supplier: Resonac

These columns separate mono and di-saccharides by combination of ligand exchange and size exclusion mode.

Supplier: VARIAN

Polymethylmethacrylate (PMMA) standards are extremely versatile as they can be used for organic GPC with a wide range of medium polarity eluents, such as tetrahydrofuran, toluene, methyl ethyl ketone and ethyl acetate.

Supplier: Resonac

Gel permeation columns (GPC) packed with tetrahydrofuran (THF), which has a wide pore size distribution designed for high linearity of the calibration curve.

Supplier: TOSOH Bioscience

Toyopearl resins can be used in organic solvents or mixtures of organic solvents and water. The compatibility of DMF with Toyopearl also permits the separation of hydrophobic substances such as polystyrenes.

Supplier: Resonac

The CLNpak EV are styrene divinylbenzene copolymer based columns suitable for the fractionation of residual pesticides in foods.

Supplier: Resonac

Semi-micro columns for Asahipak GF-310 HQ. Effective for drug analysis in biological samples by using the column-switching method to remove proteins.

Supplier: TOSOH Bioscience

These columns are designed for GFC of water soluble organic polymers, polysaccharides, oligosaccharides, DNA and RNA. They are based on a hydrophilic polymethacrylate matrix, which is stable from pH 2 to 12 and in aqueous eluents with up to 50% polar organic solvent.

Supplier: TOSOH Bioscience

TSKgel® SW size exclusion columns are widely used for aqueous analysis and isolation of proteins, antibodies, enzymes, nucleic acids and other biological macromolecules.

Supplier: Resonac

A complete range of general purpose gel permeation columns (GPC) packed with tetrahydrofuran (THF). Columns packed with other solvents are also available. Please enquire for further details.
