The molar mass determination by osmometry is one of the most important methods for evaluating  the number average molecular weight Mn. This is an important parameter for the interpretation of kinetic data in polymerization and copolymerization reactions. The method is also of interest for prepolymers with lower molar masses.

Vapour Pressure Osmometry by PSS USA

 

PSS provides sample testing service using vapour pressure osmometry measurements of polymers with masses Mn <  10000 g/mol in toluene and ultra pure water. A test includes the determination of the device scaling factor and the measurement at four different sample concentrations. The number average molecular weight Mn and the second virial coefficient A2 is evaluated graphically.


Results provided to the client:

  • number average molecular weight Mn
