Polymer Standards for GPC/SEC

     

Agilent GPC SEC Calibration Kits  Calibration Kits 

Agilent offers a wide range of polymer standards kits for conventional GPC/SEC column calibration or for calibrating light scattering and viscometry detectors. The kits are in boxed sets of ten different polymer standards covering a particular molecular weight range, to be used with organic and aqueous, medium polarity and polar solvents. Every individual polymer has its own Certificate of Analysis of the analytical conditions and values, such as Mp needed for constructing a calibration plot. The polymers are chosen to give equidistant calibration points on a logarithmic MW scale, providing a more uniform calibration curve.

 

Polystyrene (PS) Kits 

Polystyrene standards are the first choice for many organic solvents, either for conventional GPC column calibration or for calibrating light scattering and viscosity detectors. Our comprehensive Certificates of Analysis provide full information for the User, whatever the application.

Each kit contains 0.5 g of 10 different molecular weight standards.

 

Features

  • Compatible with most organic solvents
  • Certificate of Analysis meets international protocols
  • Calibration capability for virtually all applications

Wide range polarity calibrants for GPC/SEC 

Polymethylmethacrylate (PMMA) standards are extremely versatile as they can be used for organic GPC with a wide range of medium polarity eluents (eg THF, toluene, MEK, ethyl acetate), as well as the more polar organic eluents (eg dimethylformamide, dimethylacetamide, hexafluoroisopropanol). The MWs are selected to provide equidistant calibration points for greater accuracy, covering from 600-1.5 million MW.

Each kit contains 0.5 g of 10 different molecular weight standards.

 

Features

  • Many solvent options increase applicability
  • Stringent quality control improves performance
  • Proprietary manufacturing methods ensure consistent supply

Low polydispersities for GPC/SEC  

An exciting new range of linear polyethylene standards is now available with low polydispersities (1.06 to 1.3) for GPC/SEC calibration. These have been configured into a calibration kit of ten standards from 540 to 1.5 million molecular weight, which is supplied with comprehensive calibration data. This kit is the ideal standard for use with polyolefin polymers, and is designed for direct GPC/SEC column calibration in solvents such as TCB and oDCB at temperatures in the range
135-180 °C.

The E-MW-10 kit contains 0.1 g of 10 different molecular weight standards.

 

Features

  • Low polydispersity standards, typically between 1.06 to 1.3
  • Ideal for use with polyefin polymers

Hydrophilic polymers for GPC/SEC 

These hydrophilic polymers are suitable for both aqueous SEC and organic GPC using the majority of polar organic solvents. Polyethylene glycol (PEG) kits cover the lower molecular weight range, where Polyethylene oxide (PEO) kits cover the higher molecular weight range. The kits are chemically similar and therefore can be used together to cover a wider molecular weight range.
Each PEG kit contains 0.5 g of 10 different molecular weight standards.
Each PEO kit contains 0.2 g of 10 different molecular weight standards.

Polyethylene glycol is now available in the time saving and easy to use EasiVial format, a combined PEG/PEO is also available.

 

Features

  • Suitable for both aqueous SEC and organic GPC
  • Also available in the time saving EasiVial format

Pullulan Polysaccharide Kits  

Suitable for GPC using aqueous or polar organic eluents, this pullulan polysaccharide kit consists of several simple sugars together with some relatively narrow polydispersity linear macromolecules of maltotriose units.

Each kit contains 0.2 g of 10 different molecular weight standards.

 

Features

  • Comprehensive format provides full MW range in one handy kit
  • Also available as individual standards

Water soluble calibrants for GPC/SEC  

The polydispersity of these polymers is not particularly narrow (typically between 1.30 - 1.75), however, they are very useful water soluble calibrants, as the Mp values are well characterized.

Each kit contains 0.2 g of 10 different molecular weight standards.

 

Features

  • Useful water soluble calibrants
  • Polydispersity is typically between 1.30 - 1.75
