Membrane Characterization Standards

PSS has made available three lines of reference standards for the fast and robust GPC/SEC characterization of membranes in their native environment (swelled state). These reference standards can be used to prepare stock solutions for filtering experiments.

 

The membrane standards feature the following properties:

  • Broad Molar Mass Distribution for all types of membranes with different pore sizes
  • Detailed product certificate of analysis with
    - Molar Mass Averages Mw and Mn
    - Integral Molar Mass Information
    - Mmin
    - Mmax 
    - Radii of Gyration Rg,min and Rg,max
