The column works fine for what we do for the most part but the fact that arabinose and mannose practically co-elute makes it difficult to close mass balance of sugars when data calls for it

Mixed-Mode SEC with Shodex GS Series Columns
Record: 902
Category: Column Selection
Product: GS series
Sample: Proteins/Impurities
Question
Can Shodex GS series columns be used in mixed-mode (SEC + ionic interactions) to separate proteins or impurities with similar molecular weight?
Answer
Yes. Shodex GS series columns (GS-HQ family) combine size exclusion chromatography with secondary ionic interactions, which allows separation of compounds that have similar molecular weights but differ in conformation or charge.
The GS-520 HQ was historically used in protein recovery applications, but since it has been discontinued, the GS-320 HQ is the recommended alternative.
Resolution depends strongly on eluent conditions, so optimization of salt concentration and organic solvent content may be required.
