Understanding GPC/SEC - Finding the Right Particle Size and Pore Size

Want to understand what the correct criteria for column selection should be based on? If so, this tutorial is for you...

Thumbnail_T4.pngSeparation Science, in collaboration with PSS, has developed an on-going series of tutorials looking at best practice and troubleshooting for GPC users. These tutorials are available free of charge requiring just a simple registration process.

Following on from the previous tutorial 'Unexpected Peak Shapes', this presentation will move on to discuss in more detail how to avoid strange peak shapes in GPC/SEC and on what the correct criteria for column selection should be based on.

If the question 'I have completely new samples and need to identify the best columns to analyse them with', sounds familiar then this tutorial will help you out. 

Topics covered include:

  • column characteristics
  • why we have different particle sizes
  • why we have different pore sizes
  • how to take advantage of particle and pore size to improve your methods
