Do you find weird peak shapes in your chromatograms? Not sure if they are real or artifacts?

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.

The second tutorial in the series, titled 'Unexpected Peak Shapes' provides strategies for understanding peak shapes, and what to do when they don't look as expected.

In this tutorial we'll learn how to verify if a GPC / SEC chromatogram is realistic or not. You will learn why some peak shapes occur, why this happens and how to address these issues to keep your analyses on track.

Topics covered include:
- typical GPC/SEC chromatograms
- what should be expected
- artifact or not?
- sample preparation issues
- column issues
