Absorbance and quantitative Spectroscopy

In order to test the OtterVIS LGL spectrophotometer and the new UART-Version, I prepared some crystal violet solutions: 0.001m, 0.002m and 0.003m. The lightsource was a halogen lamp connected with a very simple optical fibre to the kuvette. The baseline was taken with  suitable integration parameter (nice feature). The scan of each solution was saved and plottet with octave.

I measured the solutions with my old but professional MN-NANOCOLOR UV/Vis.

The results of the OtterVIS is not bad! And there is a lot of room for improvement in the Soltware etc.
