Determination of Organic Compounds in the Smog of Mosquito-Repellent Incense by Adsorption-Thermal Desorption-GC/MS

The organic components in the smog of mosquito-repellent incense were analyzed qualitatively and semi-quantitatively by-adsorption-thermal desorption with gas chromatography-mass spectrometry. 52 kinds of compounds are identified in two kinds of solid mosquito-repellent incenses, including phenolic compounds, alcohols, aldehydes, aliphatic hydrocarbons, aromatic hydrocarbons and so on. Some compounds are poisonous to people’s health. The principal components in the smog of mosquito-repellent incense A are allethrin(30.06%), 1,6-Anhydro-β-D-glucopyranose(19.4%), azulene(13.9%), while the principal components are 1,6-Anhydro-β-D-glucopyranose(24.4%), azulene(14.4%), tetradecane(5.91%) for the mosquito-repellent incense B.
