Hey, Terry. Good to see you're still going strong. I found a site that shows/tells how to make one and since you seem to like making things yourself it may be more beneficial to go this route. Anyhow, I don't know if it is the correct one you need or not but check it out. Let me know if you come up with something.
The site is at: http://www.rsc.org/Education/EiC/issues/2007Sept/BuildYourOwnSpectrophotometer.asp Take care my friend and God bless.

I went to ebay and discovered that there are many devices that have that label. Can anyone here tell me what type of spectrophotometer I need to accurately determine ppm in CS? Where would I be likely to find a used (lower-priced) one? I remember Bob Burger once said that he had paid $150 for his used one, but I don't see any prices that low on ebay.
