Visible/Ultraviolet Spectrophotometers

UV-VIS Spectrophotometry is defined as an analytical technique capable of determining the presence and/or concentration of an analyte of interest, based on measurements of absorption/transmission of electromagnetic radiation, in the ultraviolet and visible regions of the electromagnetic spectrum.
