The main components include the light source, monochromator, sample holder, detector, and the output system, all of which work together to measure light across various wavelengths. Spectroscopy is the technique of splitting light that consists of various wavelengths into components that correspond to those wavelengths. Prisms and diffraction gratings are typical dispersive elements. The liquid sample is kept in a cuvette. Then the beam of light is passed through the. The instruments used in spectroscopy consist of several common components, including a source of energy that can be input to the sample, a means for isolat- ing a narrow range of wavelengths, a detector for measuring the signal, and a sig- nal processor to display the signal in a form convenient. A means for isolating a narrow range of wavelengths. It typically emits light across a.
