UV-Vis Spectrophotometer

In our research, UV-Vis spectroscopy is routinely used for the qualitative and quantitative characterization of analytical solutions during dissolution studies, catalytic development, and various other aqueous phase experiments. We also employ UV-Vis scattering in sedimentation studies to understand the stability of suspensions containing nano- or micro-scale particles.
