Spectrophotometer is an instrument used to measure the transmission or reflection of light of a specified wavelength passing through a medium. The idea is that the amount of light absorbed by the medium would be proportional to the concentration of the material or solute present in the medium. So, using this principal, the concentration of a solute in a solution is hence measured by the absorbance of light at a particular wavelength. To measure a sample, the solutions would be placed in a cuvette and placed in the machine after adjusting wavelength and calibrating to zero.
