| titleOfInvention | Rapid detection method for sulfur compounds in cigarette sidestream smoke |
| abstract | A method for rapidly detecting sulfur compounds in cigarette sidestream smoke is characterized by comprising the following steps: the method comprises the steps of adopting an adsorption tube made of spherical modified copper-loaded Y molecular sieve particles to capture sulfur compounds in cigarette sidestream smoke, then desorbing the smoke by using a desorption instrument, and measuring the desorbed gas by adopting a real-time direct analysis mass spectrum (DART-TOFMS). The rapid and accurate qualitative and quantitative determination of sulfur compounds in the cigarette side stream smoke is realized. The method combines the absorption tube trapping with the real-time direct analysis mass spectrum analysis for the first time, is applied to the determination of the sulfur compounds in the cigarette sidestream smoke, has simple pretreatment, is more rapid and convenient for the real-time determination of the instrument analysis compared with the traditional analysis determination, can cover the analysis of different sulfur compounds, avoids the complex operations of different types of sulfur compounds and different pretreatment in the traditional test, has no introduction of organic solvent in the whole pretreatment process, and is more environment-friendly compared with the traditional analysis. |
