固相微萃取(SPME)在煤气中萘的快速分析中的应用研究

Application Research of SPME Combined with GC on Rapid analysis of Naphthalene in Gas

文章采用固相微萃取(SPME)技术与气相色谱联用方法,快速、准确地分析了煤气中的萘,优化了SPME的萃取方法。应用该方法对家用煤气中的萘进行测定,加标回收率为84.1%以上,证明了该方法对于煤气中的萘分析的可靠性和稳定性。

The article introduces the method of solid-phase micro extraction （SPME） combined with gas chromatography （GC） to analyze the naphthalene in gas rapidly, which optimizes the SPME technology. If the method is applied for the analysis of naphthalene in gas, the recovery of standard addition can be more than 84.1 %, confirming the reliability and feasibility of the method in the processes of analyzing the naphthalene in gas.
