Research on Determination of Total Volatile Organic Sulfur Compounds in the Atmosphere
大气中总挥发性有机硫化物检测方法的研究

A detection technology was established comprising trap,desorption,oxidation and UV fluorescence determination process,and used for the test of total concentration of trace volatile sulfur compounds(VSCs) in the atmosphere.A cryogenic trap-thermal desorption device was developed,integrating the advantages of solid retention method and cryogenic condensation method,which was applied to capture and enrich trace volatile organic sulfur compounds.Under high temperature and combustion-supporting gas,the VSCs were...
