Figure 3. Py/TD-GC-MS chromatograms (SIM mode, m/z 79) from Type-C reference PVC samples with (A) DEHP and c-MCCP mixtures, and (B) DINP and c-MCCP mixtures. The very broad and wavy undulating response of c-MCCP is clearly differentiated from the sharp single spike of DEHP, and the narrower cluster of multiple isomeric congener peaks of DINP.
