Comprehensive two-dimensional gas chromatography (GC×GC) provides enhanced
resolving power and peak capacity by combining two different separation
mechanisms in one analysis. This allows for more detailed separations and more
complete characterization of complex matrices. Here we show the py-GC-MS
and py-GC×GC-MS profiles of polyethylene (PE) to prove the advantages arising
from coupling pyrolysis and GC×GC.
