Japanese lacquer film called “Urushi” is a natural polymer that has been used as a paint and adhesive for living-wares and craft-wares for approximately 8,000 years. “Urushi” has a complex structure that researchers are trying to understand using pyrolysis-gas chromatograph/mass spectrometer (Py/GC/MS) system. Recently, we developed a new gas chromatograph/high resolution time-of-flight mass spectrometer (GC/HR-TOFMS) system that can be used for comprehensive two-dimensional GC (GCxGC) measurements. Additionally, we developed a unique combination electron ionization/photoionization (EI/PI) ion source that can be used with this GC/HR-TOFMS system. In this work, we measured “Urushi” samples using this unique Py/GCxGC/HR-TOFMS system in combination with our new combination EI/PI ion source.
