摘要 Benzene derivatives are volatile organic compounds commonly present in the atmospheric environment, which are toxic and complex in composition. They have become a key regulatory object in China's atmospheric environment management. In this paper, Shimadzu Nexis GC-2030 gas chromatography was used to simultaneously detect eight benzene derivatives. According to the Environmental Monitoring - Technical Guideline on Drawing and Revising Analytical Method Standards (HJ 168-2010), the monitoring methods for benzene, toluene, ethylbenzene, p-xylene, m-xylene, isopropylbenzene, o-xylene, and styrene in the Stationary Source Emission - Determination of Benzene and Its Analogies - Bags Sampling/Direct Injection - Gas Chromatography (HJ 1261-2022) are verified, and their linear relationships, detection limits, precision and accuracy are analyzed.
