I created a spectrometer that produces nice clean wavelengths, I calibrated it using a fluorescent bulb. from that I can create a graph from the data. after which, I use the known position to of emission lines (Blue: 405.4 nm, Bright Purple: 436.6 nm, Brightest Green: 546.5 nm) to scale the graph to its proper wavelength.
I have done all of that, I'm planing on using a xenon bulb with a Borosilicate test-tube filled with water. The water will have unknown contaminates. But from the xenon spectrum of the water, how do I known whats in the water?
Ive looked at beer's law, but that just tells you the consecration of the unknown substance in the water. I have model my spectrometer from commercial ones that from a test tube and a xenon bulb can tell you whats in the water.
There must be some formula describing the absorption spectrum of a element and how to find that element inside a spectrum of unknown.
