WEBINAR: Improve Your Chromatography with Refractive Index

August 27, 2020 at Noon–1:00pm EDT
Webinar via Zoom

Free to Everyone

Summary

Gel Permeation Chromatography (GPC) plays an essential role in determination of dispersity and molecular weight of polymers and complex molecules. Calibration is done using polymer solutions such as polystyrene in organic solvents, and uncertainties in preparation of the standard can often carry over to uncertain measurement results.

This webinar from Anton Paar will focus on how you can minimize uncertainty — and expensive errors - with a fast, highly-precise refractive index measurement. After the webinar, you will have a better understanding of how a refractometer can improve your chromatography.

Featured topics in this webinar will include:

  • GPC calibration process
  • The role played by dn/dc values
  • How a refractometer can improve the GPC calibration process
  • Requirements and the specifications your refractometer must meet
