Instrument model: Agilent 7890A GC-5975C MS (left), Thermo Trace 1300-ISQ 7000 (right)

    Instrument function: This instrument is used for the detection of small molecular weight, easily gasified compounds, compounds for mass spectrometry identification, and semi-quantitative.

    Instrument configuration: automatic sampler, EI source, Quadrupole Mass Spectrometer, which can carry out full scan, SIM, etc.

    Application:

（1）Identification and semi-quantification of lipids in sedimentary rocks of key geological periods, such as alkanes, aromatics, fatty acids, fatty alcohols, fatty ketones, etc.

（2）Identification and semi-quantification of specific biomarkers in sedimentary rocks or sediments, such as hopane, hopicacid, hopanol, HBI, long-chain ketenone, long-chain diol, monoether and diether compounds.
