3. Pyrolytic gas chromatography analysis
Pyrolytic gas chromatography of organic compound with high boil-
ing points was conducted for the degradable degreaser. The spectrum is
shown in Figs. 6.26 and 6.27. It can be seen from the figure that the
pyrolysis chromatographic peak of organic compounds in the sample
with high boiling points is similar to that of surfactant AES, which
proves the existence of surfactant AES in the degreaser.
