32368Re: Testing for methanol
- Oct 3, 2005actually there is a protocol for that. It uses fuchsine and some
other compounds (potassiumpermaganate). I don't think I still have
the protocol. Our local pharmacist used to sell these kits and he
told me that some compounds (like fuchsine) are hard to get (must
also be expensive).
I tested the kit in the lab with 0%,1%, 50% and 100% methanol but
found the results to be dissapointing. I suspect that one of the
compounds was old and therefore didn't work.
After that I didn't bother to get a fresh kit, throwing away a
generous methanol fraction is more then sufficient and saves the
trouble for testing every time. Also I don't know how sensitive the
kit was but if it is very sensitive you can drive yourself mad. You
will nearly always find a positive result!
