Hello,
I'm an amateur scientist in Denver, CO, looking to expand my lab a
bit.  I would like to be able identify different compounds in a
solution of (whatever), and have a computer identify the ingredients.

I *assume* I need:
1) a spectrophotometer with a computer interface and software
2) a way to seperate the individual compounds using chromatography
(HPLC?)
3) a database to identify the individual spectra
4) I'm not sure what the most useful spectra are - IR / Vis / UV?
5) Are there any free computerized databases out there?

This is brand new territory for me.  What used system, which I might
find on Ebay would be the best 'bang for the buck'?

Thanks for your advice!
Best regards,
-Mark
