Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a capture, analysis, oxidation, and FPD detection technology for the detection of trace total volatile organic sulfides in the atmosphere. Self-developed low-temperature capture-thermal desorption device Combining the advantages of solid retention method and low temperature condensation method, it is applied to the enrichment of trace volatile organic sulfides in the atmosphere. The enriched organic sulfides are fully oxidized to sulfur dioxide under the action of high temperature and combustion-supporting gas, and FPD detection is used. The concentration of total volatile organic sulfides in the atmosphere can be obtained indirectly. The capture temperature of the method is 5℃, the desorption temperature is 150℃, the oxidation temperature is 1000℃, the precision is 5.46%, and the recovery rate is 99.6%～109.2%. . Using this device, the content of trace total volatile organic sulfides in the atmosphere from February to April 2011 was determined to be 42 to 195 ng·m-3.
