I took UV Visible spectrum of 1ppm Caffeine solution. It showed a huge amount of noise in the UV region. The absorbance was more than 2. Hence I reduced the concentration of the solution to 0.1ppm and 0.01ppm. Still, the absorbance was more than 2 and had a huge amount of noise in the UV region. The solvent used was water. What could be the possible reasons for the same? Files are attached below.
