Every peptide bond absorbs near 214 nanometres, making it the universal peptide detection wavelength. It sees everything peptidic, including impurities and the copper-free form, and it is where purity by area is normally calculated.
It cannot tell whether copper is attached.
Only the copper complex absorbs in the visible, through its d-to-d transitions. A detector set in that range sees the complex and ignores copper-free peptide and most impurities. Its signal is weaker than the ultraviolet one, but it is specific.
Together the two channels show whether the main peak carries its metal.
A method reporting both channels has demonstrated the complex is intact through analysis, which is the question the copper-free impurity raises. Where only the ultraviolet is reported, that question is open.
