I am still in the planning stages of a purchase of an HPLC. I would like to capture aliquots of material, as they come out of the column, then concentrate them for further analysis on an HPLC. For dissolved resins (acrylics, alkyds, etc.) in a GPC or reverse-phase system (depending on how I need to perform the tests), what would be a good, robust, quiet system for concentration? In the past, I've used vacuum centrifuges for biochemistry/genetics research, but the eppendorf tubes which are utilized are likely too small and I am unaware of systems that could handle larger volumes.
Has anyone performed similar work that could weigh in on this?
Thanks!
