| titleOfInvention | A method for detecting the content of polycyclic aromatic hydrocarbons in burning incense products |
| abstract | The invention relates to the field of burning incense product testing, and provides a method for detecting the content of polycyclic aromatic hydrocarbons in burning incense products, comprising the following steps: (1) collecting smoke after burning incense; (2) adding to the smoke Dichloromethane, add polycyclic aromatic hydrocarbons extractant after ultrasonic treatment, fully enrich polycyclic aromatic hydrocarbons, and then elute through the eluent, evaporate the eluent by rotary decompression or blow it to near dryness with gentle nitrogen, add ethyl acetate Dissolve and add the internal standard as the sample to be tested; (3) prepare a series of standard working solutions containing different concentrations of the target, measure by gas chromatography-tandem mass spectrometry, and draw a standard curve; (4) by gas chromatography-tandem mass spectrometry Measure the sample to be tested, measure the secondary selected ion peak area ratio of the target substance and the corresponding internal standard substance, and substitute it into the standard curve to obtain the content of various polycyclic aromatic hydrocarbons. The detection method of the invention fills in the blank of the prior art, and has the advantages of simple and quick operation, accurate detection results and good repeatability. |
