Detection method of dilauryl thiodipropionate based on gas chromatography-mass spectrometry and application thereof

The invention relates to a detection method of dilauryl thiodipropionate based on gas chromatography-mass spectrometry and application of the detection method. The method comprises the following steps: by taking dilauryl thiodipropionate as a standard substance, adding acetonitrile for dissolving to prepare a standard working solution; detecting the standard working solution by adopting gas chromatography-mass spectrometry to obtain a gas chromatography-mass spectrometry spectrogram of the standard working solution, and constructing or not constructing a standard curve; taking a to-be-detected sample, and adding acetonitrile to prepare a to-be-detected sample solution; and carrying out detection and result analysis on the to-be-detected sample solution by adopting gas chromatography-mass spectrometry. The method provides a reasonable basis for qualitative and quantitative analysis of dilauryl thiodipropionate, and the detection method is high in accuracy, precision and sensitivity, meets the requirements of m
