By using PDA and MS in LC, it is possible to qualitatively analyze colored extracts.
Many organic materials (resins) may discolor due to aging and other factors. The causes include the formation of conjugated double bonds within the polymer, the degradation of additives contained in the resin, and the transfer of surrounding substances, among others. When the degradation of additives is the cause, the responsible substances can be analyzed by elution using methods such as LC or GC. Here, we provide an overview of the causes of resin discoloration and analysis methods, and introduce a case where the coloring substances responsible for yellowing in polyurethane were separated by LC and qualitatively identified using a combination of PDA and MS.
