Greetings I have a extracted substance that I’ve been able to redisolve and  separate into three phases, but what they are and in what concentrations I can only guess. My chemistry budget is limited.how much should it cost to have four samples analyzed?and where are these available?

Have you thought of building a spectrometer? There are several ways to do it within 50 bucks. I used refraction grating, a hd web cam and there are several programs out there that will process the data. I used it to measure concentrations of chlorophyll.
