While conventional calibration for gel permeation (GPC) and size-exclusion chromatography (SEC) are useful for polymer characterization, there are inherent disadvantages in these analyses. Adding multi-angle light scattering (MALS) detection can help overcome the challenges faced with single-detector chromatography. For more complex polymers, asymmetric flow field-flow fractionation (AF4) offers additional capabilities.

Read this new e-book to learn about:

  • Why an absolute measurement with MALS is a more accurate than a single-detector measurement
  • The simplicity of plumbing a MALS detector inline with an HPLC system and concentration detector (such as UV or RI)
  • How MALS detection increases experimental throughput by eliminating calibration steps
  • How SEC-MAS compares to AF4-MALS for measuring molar mass distribution
  • The advantages of choosing AF4-MALS for larger and problematic polymers
