Hi,
I wondered if anyone here had tried to use some of the homemade spectrophotometers and https://spectralworkbench.org to measure nitrate or indeed other colourmetric assay rather than a test kit. I am thinking about it but its quite a big project so before I start I wondered what I might expect.

I understand the theory and use much more expensive versions in my day job. I just wondered if these back to basic ones actually work. From what I can seen I can get an emission spectrum from these spectrometers. Plotting intensity (or more correct absorbance vs concentration) will give me a calibration curve for measurement of a sample of tank water which has been taken through whatever test kit you are measuring for.
