[Analysis Case] Pyrolysis GC/MS Double Shot Method, Identification of Plastics and Additives
Composite analysis using TG-DTA and GC/MS.
By combining TG-DTA (thermogravimetric-differential thermal) analysis with GC/MS analysis, it is possible to select optimal temperature conditions to identify unknown polymer materials and the volatile organic compounds they contain. By investigating the pyrolysis temperature of the plastic parts of commercial products and continuously performing GC/MS measurements under two conditions—gentle heating below the pyrolysis temperature (thermal desorption method) and subsequent rapid heating at high temperatures (pyrolysis method) using the double-shot method—it was determined that this plastic is AS resin and contains the antioxidant additive IRGANOX 1076.
