Acclaim SEC LC Column

Size-Exclusion Chromatography (SEC) Columns for Separating Water-Soluble Polymers

Thermo Scientific™ Acclaim™ SEC-300 and SEC-1000 columns are a family of high-performance size-exclusion chromatography columns specifically designed for the separation of water-soluble polymers and oligomers. Acclaim SEC columns are available in two pore sizes, 300 ? and 1000 ?, and are optimized for separating a broad molecular weight range. Water-soluble polymers cover a wide range of highly varied families of products, both of natural or synthetic origin, and have numerous uses in pharmaceuticals, medications, cosmetics, food products, and industrial processes, to name a few.

Column features include:

  • Proprietary monodispersed, multipore, hydrophilic resin: no inflection points in calibration curve.
  • Two columns with different pore sizes offer wide linear range (100 to 1,000,000 Dalton).
  • Availability of small particle sizes packed in 4.6 × 300 mm dimension allows for high-resolution analysis with reduced solvent consumption.
  • Stable surface bonding with low column bleed and compatibility with UV, RI, MS, ELSD and Thermo Scientific Dionex Corona™ Charged Aerosol Detectors.

These columns are packed with spherical, monodispersed, hydrophilic polymethacrylate particles synthesized by multipore particle synthesis technology. Combined with the use of small particle sizes (5 ?m for Acclaim SEC-300 and 7 ?m for Acclaim SEC-1000), they provide high-resolution and good linearity of the calibration curve for accurate and reliable analysis of a variety of water-soluble polymers.

The Acclaim SEC-1000 uses polymethacrylate particles with a nominal pore size of 1000 ?, resulting in a broad linear calibration range from 1,000 to 1,000,000 Dalton. Therefore, it is suitable for characterizing high molecular weight polymers. The Acclaim SEC-300 uses polymethacrylate particles with a nominal pore size of 300 ?, giving a linear calibration range from 100 to 50,000 Dalton. As a result, this column offers good resolution for lower molecular weight polymers or oligomers.
