“Allround“ SEC-columns for initial analysis of unknown samples For Size Exclusion Chromatography (SEC) of technical or biological polymers, Tosoh Bioscience GmbH offers a newly developed hydrophilic rigid resin showing little swelling and shrinkage in water mixtures or pure organic solvents. Small resin particles (4 µm) with narrow particle size distribution packed into 6 mm ID columns with 15 cm length demonstrate the superi…

EcoSEC Elite and EcoSEC HT GPC/SEC Systems enable efficient polymer characterization

TSKgel GPC columns for organic-soluble polymers are packed with spherical particles composed of polystyrene crosslinked with divinylbenzene (PS-DVB)

Ca++Pure-HA is a hydroxyapatite resin used in the chromatographic separation of biomolecules. Ca++Pure-HA is specifically developed for the purification of monoclonal and polyclonal antibodies, the separation of antibody isoforms, isozymes, the purification of antibody fragments, and the isolation of single-stranded from double-stranded DNA. Ca++Pure-HA resin has been sintered at high temperatures for increased mechanical a…

TOYOPEARL NH2-750F offers a high binding capacity across a range of pH values and conductivities

Widely considered the premium columns for analyzing biopolymers by GFC, TSKgel G2000SWXL, 5 μm columns are an excellent choice for small proteins and peptide separations.

The TSKgel Alpha-4000 column is packed with rigid, porous polymer beads which show minimal shrinkage or swelling in polar organic solvents (methanol, acetonitrile, DMSO, isopropanol, THF, and HFIP). This column is stable in a wide variety of organic solvents at concentrations up to 100%. The main application area for the TSKgel Alpha-4000 column is the analyses of polymers that are soluble in polar organic solvents up to 1…

TOYOPEARL HW-55S resin is a hydroxylated methacrylic polymer for size exclusion chromatography

TSKgel SW-type columns for size exclusion/gel filtration analysis of antibodies and other proteins are silica-based. A hydrophilic diol-type bonded phase shields the silica surface from interacting with protein samples.  TSKgel SW-type columns contain more pore volume per unit column volume, which results in higher MW selectivity or better resolution. In addition, they show low adsorption and well-defined pore size distribu…
