Thank you Fadedawg for taking the time, that was a great answer and it makes perfect sense with the applications I've seen so far. Do you mind if I share your answer on some other forums?
Mysunnyboy, I am not sure it's ever not too early for you, but thanks for your contribution anyway.
Right, BUT it CAN separate solvents very well:

What I am not sure of is if that can be accomplished somehow with a benchtop and not those tube fed cells...
Distillation seems to be the most common answer in the industry, but I also now see centrifuges being used more often for separation and preparatory chromatography.
I've always wanted one of those benchtop centrifuges, starting with curiosities stemming from molecular gastronomy. I'm wondering...
