A combination system of simultaneous thermal analysis(STA),Fourier-transform infrared(FT-IR) spectroscopy and GC-MS was established for simultaneously determination of pyrolysised products of the pectin samples under nitrogen or nitrogen-oxygen atmosphere.According to the pyrolysis behavior of pectin,26 substances were detected at three temperatures(243℃,270℃ and 335℃) on line with the system.
- simultaneous thermal analysis,
- FT-IR,
- GC-MS,
- pectin pyrolysis
