The invention provides a method for detecting 10 halogenated carbazole compounds in marine sediments, belonging to the technical field of marine sediment detection. Or the sample to be tested is separated and retained by the chromatographic column into the mass spectrometer, and the accurate mass number is collected, the mass spectrum voltage is optimized, the acquisition parameters are scanned, and the 10 halogenated carbazole compounds are accurately identified and quantified. The invention improves the extraction effect of halogenated carbazole compounds by improving the preparation method of C18 bonded silica gel, and then utilizes the qualitative and quantitative function of gas chromatography-triple quadrupole tandem mass spectrometry to detect halogenated carbazole compounds in marine sediments, and has the operation Simple and fast, can effectively reduce the interference of matrix components, high sensitivity, high resolution and so on. |
