    Abstract:

    With the detection technology of IR、GC-MS、EDS、XRDand TOF-MSꎬ the identification of the un ̄
    known substance was successfully obtained.This article introduced the test process in the laboratoryꎬ qualitative and
    quantitative analysis of the results.Finally the various test methods for identification of unknown material chemical
    composition were summarized .Generally the analysis of unknown component starts from the analysis of the microscopic
    functional group by means of infrared spectroscopyꎬand then with the help of chromatographic separation and purifica ̄
    tion technologyꎬfinally qualitative and quantitative analysis can be summarized by the X-ray diffractionꎬ spectrosco ̄
    pyꎬ mass spectrometry and other techniques.
