Since free atoms exhibit specific discrete energy levels (e.g. the hydrogen Blamer series), to identify which atoms are present you need to measure which wavelengths are being absorbed, not just that there is absorption. To be sensitive to wavelength, you need to disperse the light, and that means a monochromator.
