Description

Spectrophotometers determine the composition of a solution (or the concentration of certain substances within a solution) by measuring how the solution absorbs a particular wavelength of light. By varying the wavelengths in each measurement, one can take a spectrum of a solution and ascertain the composition. More advanced spectrophotometers can measure beyond the visible spectrum, providing readings for ultraviolet and infrared wavelengths.
