Abstract: 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.

Key words: STA, FT-IR, GC-MS, pectin pyrolysis
