Spectral Signature of the Eluting Species in the GPC Analysis
PDA detector response images for the eluting species in the GPC analysis performed on lignin oil, liquid products, and residues obtained with no added catalyst (control experiment) and in the presence of 15%Ni/Nb2O5 catalyst (recycling experiment). The yellow-coded dotted line in the PDA image of the solid residue (first reaction run) indicates the extension of the UV-vis absorption signal.
