The need of different monochromator slit widths for quantitative and qualitative analyses needs to be explained. Concept introduction: Monochromators are optical devices which transmit a wide range of available wavelengths, a mechanically selectable narrow wavelength band. These could be wavelengths of light or any other radiation.
