I am very interested in developing functioning analytical instruments for use as educational tools for
university settings or for use by fugal chemists or hobbiest. The global activest side of my personality
also says that making inexpensive analtical instruments available to scientists in developing countries
would have a more significant environmental impact than measuring the PCB concentration of
my local lake.

One device that has significant potential is an electrophoresis system with an electrochemical
detector. The first challange is to develop a safe and reliable HV power supply. 20 KV to 40KV
low current and stable. Maybe from a flyback transformer. Do you have any idea's or expertise
that you would care to share. I am primarily an analytical chemist and have a self taught work
knowledge of electronics. Likely an advanced novice level at best.

cheers,

R.O'B
