From Proteins to Polymers – GPC-SEC: Understanding Column Selection and Method Considerations for Your Sample
In most HPLC separations there is a wanted interaction of the sample with a chromatography packing.
When doing GPC/SEC separations, that is not the case. GPC/SEC is a noninteractive technique that separates samples based on their size in solution and not on their chemistry. This presentation will cover the common questions that should be asked when developing a robust and reproducible GPC/SEC method.
Topics will include:
Sample type: protein vs polymer
Solvent Selection and its importance
Column Choices & how to choose correctly
Calibrants
Detector & Instrument Considerations
As we discuss each topic area we’ll look at examples and provide valuable tips that can help you achieve long term reproducible and reliable results.
