"SEC Chromatography"

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

Columns for simultaneous analysis of saccharides and organic acids.

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: Resonac

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

Supplier: Merck

With their high degree of UV transmittance, low particle count, low acidity and alkalinity and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. Since separations are normally carried out under gradient conditions in analytical HPLC, we offer solvents in "gradient grade" as well as "isocratic grade". This enables to minimize the gradient effect of the solvent involved.

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

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

Supplier: Resonac

Supplier: Merck

Disodium hydrogen phosphate dihydrate ≥99.0% (by acidimetry), LiChropur™ buffer substance, for chromatography, Supelco®

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: 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: Resonac

For an efficient cleaning, reverse the flow direction.

Supplier: Honeywell Chemicals

2-Propanol (Isopropyl alcohol, Isopropanol, IPA) is a colorless solvent and is the simplest example of a secondary alcohol. It can dissolve a wide range of non-polar compounds and works well as a degreaser. Propanol-2 has a boiling point of 82 °C. Suitable for HPLC and spectrophotometry.

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.
