Abstract
The invention discloses a method for detecting complicated organic chemical raw materials. Detection analysis instruments combining four detection analysis methods are adopted, a gas chromatograph, a mass spectrometer, a nuclear magnetic resonance spectrometer and an infrared spectrometer are connected in series, the complicated organic chemical raw materials automatically and orderly enter the gas chromatograph, the mass spectrometer, the nuclear magnetic resonance spectrometer and the infrared spectrometer in a helium and vacuum conveying manner for omnibearing detection analysis, and unpredictable ingredients and elements in the complicated organic chemical raw materials are found conveniently.
Description
Technical field
The present invention relates to a kind of detection method of industrial chemicals, particularly relate to a kind of detection method of complicated Organic Chemicals.
Background technology
Mass spectroscopy can carry out effective qualitative detection analysis, but just seems helpless to the detection analysis of complex organic compound; And chromatography is that one is effectively separated determination method to organic compound, be particularly suitable for the quantitative detecting analysis carrying out organic compound, but qualitative detection analysis is then more difficult.Therefore, the effective combination of both will provide one to carry out the efficient qualitative and quantitative analysis analysis tool of complex organic compound for chemist and biochemist.As this, the technology that two kinds of methods combining get up is referred to as coupling technique, the instrument of gas chromatograph and mass spectrometer being joined together to use is called gas chromatograph-mass spectrometer.But efficient, quantitative detecting analysis recited above, be also only based on and carry out on the basis probably recognizing the material that may exist in complicated Organic Chemicals.And in some environmental sampling, cost in complicated Organic Chemicals is very complicated, have except material except may existing of can predicting, also there is a lot of unknown composition, current detection analyst, only by the data of gas chromatograph-mass spectrometer display, is lack seizure property and detect analytical for the composition being difficult to predict.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of detection method of complicated Organic Chemicals, make it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide one can to obtain diversification, many-sided data are assisted a ruler in governing a country mutually, analyze the detection method of the complicated Organic Chemicals of unpredictability composition.
The detection method of a kind of complicated Organic Chemicals that the present invention proposes, is characterized in that: comprise the following steps:
