The Solid Phase Micro Extraction (SPME) And It’s Application
Abstract: The solid phase micro extraction (SPME) is a new kind of modern instrument method before output sample. Along with people as to it's the principle develop deep with the technique into the comprehension, the new SPME equip continuously applied with the development, SPME already extensive and applied handle in the environmental protection and fluid matter, the clinical medicine, public security official's case handle, national defense etc.. Present this text as to it's principle, the conditions of extraction, coupling with other analytical technologies to proceeds the overviewed.
Keywords: solid-phase micro extraction; the conditions of extraction; coupling with analytical technologies; application; review
SPME可以成为质谱仪的进样工具。待测物于熔融石英纤维涂层处解吸,可快速导人离子化池,产生极窄峰并具有良好的信燥比率。质谱借助于分子碎片离子获取的信息可用于定性或物质鉴别。如顶空SPME与射频辉光放电质谱(radio frequency glow discharge mass spectrometry,rf-GDMS)联用检测四乙基铅(tetraethyllead,TEL)水溶液。引入rf-GDMS系统的有TEL和四甲基锡(tetramethyltin)。两者都产生能据此定性的良好图谱。
