Hi, all -

Does anyone know if there are any columns (mixed mode, similar to BioRad Aminex columns) for UPLC for sugars, acids and ethanol?

I haven't even begun to search, but I usually stop here first to ask questions.

Just curious if you were able to validate an Aquity UPLC BEH amide (1.7 um, 2.1 x 100 or similar) method for your BioRad 87H replacement? We are trying to do the same things, but have run into robustness issues, namely overpressurization issues. What type of method did you end up using? Did you encounter any overpressure and or column lifetime issues?

Thanks,

Jamie
