• Absolute Molar Mass Characterisation
  

  Multi-angle light scattering coupled to SEC or other fractionation methods can provide an absolute means for measuring the molar mass, size and distribution of proteins, polymers and particles of all sorts. Wyatt Technology's MALS also enables the elucidation of additional data such as branching, conformation, and eluent behaviour. The same instrumentation also allows observation of molecular interactions in a real-time environment. As MALS is an absolute mass and size measuring technique it is insensitive to the separation mechanism and as such is ideal for both highly variable research applications as well as routine quality assurance of previously characterised samples more

• Do you see the complete picture?
  

  Gel permeation chromatography (GPC) or also named size exclusion chromatography (SEC) is the most often used method for determining the molecular weight of natural and synthetic macromolecules. One specific strength of this method lies in the fact that by the separation process the whole molecular weight distribution is obtained. The molecular weight distribution contains much larger information for the characterization of polymer samples compared to a single value. more
