Great idea. I can measure and record all the tests for color development over time so we can see how critical time is to all the tests. I can do some of that this weekend using the bw units. Nice thing is I can save full spectrum as excel data for analysis. I’m really interested in how sharp the absorbable peak is. That magenta in nitrate means green is pretty widely absorbed. If so you can use leds with no filter. Filters are expensive. Tungsten lamps are hot and burn out.
The iodine test is impossible for me to read by eye at all. Remember for nitrate we are really measuring nitrite.
I’m interested in the 200-300nm abs for nitrate I read about. That is interesting but I have only hg lamp at 195 as a source out there. Deuterium ain’t cheap.
Anyway what test kit shall I get for this?
