Flourometers are instruments that measures the intensity of the fluorescence. The molecules of certain materials can absorb light energy of certain wavelenghts and re-emit that energy as light of a different wavelength. The wavelengths of the light absored and of the light emitted are characteristic for the substance involved. If this substance is in solution, the intensity of the light emitted is usually proportional to the intensity of light absorbed and to the concentration of the substance in solution.

Hello Mark,
ReplyDeleteThe text needs some editing, see me on Monday.
Kindly cite your references too.
Wow. So this device could be used in qualitative chemistry. Cool.
