Refractometry

Hey all, I know I've been kind of hammering the board with threads about building basic analytical instruments and the likes. I was wondering though about the utility of refractometers?

I have limited experience with these instruments, such as measuring the concentration of single component ionic solutions. The more I think about it the more I realize that in a home lab, I'm often looking for changes. Not absolute characterization.

I guess what I'm asking is, would this be as useful of a project as I think it might be?

I can see a refractometer being used for:
- Isocratic elution of chromatography columns, IE: detecting analytes without TLC.
- concentration/quantitation of compounds
- in some cases (limited) for characterization/purity assessment
- basic kinetics experiments

What made me think of it is there is a lot of inquiry about electrochemical cells IE: chlorate synthesis and this seems like a way to not "fly blind".

Looking for some community input.
