I need to check the presence (and also purity approx) of a substance in solution. I have a very good reference (10mg/1ml - the substance in water).
Can I use a refractometer to do this?
I am trying to separate the substance from several other ingredients using ether initially then water. At that point, I'd like to see what I have. Is my target in the water? If so can I ballpark the purity?
I was hoping that I could use a refractometer because I have such an excellent reference.
Can I use a standard handheld refractometer from say amazon with say a Brix scale? Or am I way off?
Obviously, there isn't a handheld refractometer I can buy that measures my specific product.
Are refractometers essentially generic? Can I get one with a standard scale and use that to measure the reference and then compare with my extract/filtrate?
