Embodiment 1
[0028] The determination method steps are:
[0029] A. Use isopropanol as a solvent to prepare the sample. The steps are: randomly take a sample of popping bead cigarettes, put the popping beads in a headspace bottle, press the popping beads, add 10mL of isopropanol solution, shake and extract, extract The solution was passed through a 0.22 μm filter membrane. Then use gas chromatography high-resolution time-of-flight mass spectrometry (GC-TOF / MS) to perform full-scan analysis on the liquid in the popping beads to obtain a full-scan map;
[0030] B. Use the database (NIST standard spectrum library) to search to determine the unknown, and screen the key components according to the semi-quantitative results of the area normalization method;
[0031] C, for the key component screened out, with n-propyl benzoate as internal standard, determine the qualitative and quantitative parameters of the mass spectrometry of each component by gas chromatography-secondary mass spectrometry (...
