The technique is sometimes complemented or combined with viscometry and polystyrene standards are available for validation of the results.
In alternative fashion, techniques such as light scattering and / or viscometry can be used online with SEC to yield absolute molecular weights that do not rely on calibration with standards of known molecular weight.
The number average molecular mass of a polymer can be determined by gel permeation chromatography, viscometry via the ( Mark Houwink equation ), colligative methods such as vapor pressure osmometry, end-group determination or proton NMR.
Experimental approaches for characterizing polymers are also common, using Polymer characterization methods, such as size exclusion chromatography, Viscometry, Dynamic light scattering, and Automatic Continuous Online Monitoring of Polymerization Reactions ( ACOMP ) for determining the chemical, physical, and material properties of polymers.
Gel permeation chromatography is often used in combination with Low-angle laser light scattering ( LALLS ) and or viscometry can be used to determine the molecular weight distribution as well as the degree of long chain branching of a polymer, provided a suitable solvent can be found.
