Utility of a System Consisting of EGA/PY-3030D and GCMS-QP2010 Ultra EGA/PY-3030D and GCMS-QP2010 Ultra

The analysis of eyeliner and museum quality paint are used to demonstrate the capabilities of a system consisting of an EGA/PY-3030D pyrolyzer and a GCMS-QP2010 Ultra. The eyeliner was first analyzed using evolved gas analysis (EGA-MS). The EGA thermogram shows that the eyeliner contains compounds with a wide range of properties - from volatile organic solvents to nonvolatile polymers. The compositional analysis of each temperature zone on the EGA thermogram was determined using a high-resolution capillary column interfaced to the GC-MS. The high temperature pyrolysis of an ancient mural paint illustrates of the value of pyrolysis-GC-MS to characterize a material of interest.
