Sample Preparation in GPC/SEC

Want to get a better understanding of the various sample preparation procedures available for GPC/SEC analysis, and what to consider when selecting one? If so, this tutorial is for you...

Separation 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 'Finding the right particle size and pore size in GPC/SEC', this presentation will move on to answer the question, 'how do I prepare samples for successful GPC/SEC analysis'. You will also discover how to avoid typical mistakes when preparing solutions of your samples and calibration standards. .

Sample preparation is a huge field, especially when it comes to the analysis of biopolymers such as starch or lignins where multistep procedures are required that are very specific for each class, and sometimes for each type of sample. 

Topics covered in this tutorial include:

  • solvent considerations
  • concentration recommendations
  • general dos and don'ts when working with macromolecules
