广泛应用于涉及环境、生物和药用样品、食品和饮料、香精香料、法医和毒理学以及产品检测的各种领域。典型应用包括: - 水样和空气样的环境分析 - 聚合物和固体样品中痕量杂质的顶空分析 - 万亿分之一级别的气味分析 - 食品的风味分析 - 纵火和爆炸物样本的法医分析 - 血液中酒精或尿液及血清中药物成分的毒理学分析 ## SPME[](https://www.sigmaaldrich.com)是如何工作的? SPME 采用一种涂有萃取相的纤维:该萃取相可以是液体(聚合物)、固体(吸附剂)或两者的组合。涂覆好的纤维置于保护性针管内,并连接到一个类似注射器的固定架上。 当纤维接触样品时,样品中的待测物会从样品基质中向固定相分配,直至达到平衡。纤维的涂层通过吸收(液体涂层)或吸附(固体涂层)从样品中萃取化合物。 经过规定的萃取时间后,将纤维取出并直接插入色谱仪(通常为[](https://www.sigmaaldrich.com)[气相色谱仪(GC)](https://www.sigmaaldrich.com/SG/zh/applications/analytical-chemistry/gas-chromatography)或[高效液相色谱仪(HPLC)](https://www.sigmaaldrich.com/SG/zh/applications/analytical-chemistry/liquid-chromatography/small-molecule-hplc))中,进行脱附和分析。在GC中,分析物的脱附通过加热进行;而在HPLC中,则使用溶剂将分析物脱附至液相中。 ## SPME[](https://www.sigmaaldrich.com)的优势 SPME 将分析物的采样、分离和富集整合为一个简单的步骤。通过控制纤维涂层的极性和厚度、保持一致的采样时间以及调控其他若干萃取参数,SPME 使分析人员能够确保从样品中获得高度一致且可量化的结果,即使分析物浓度较低也是如此。 SPME的其他优点包括: - 无溶剂 - 易于自动化 - 对样品无损 - 适用于几乎任何样品或基质 - 所用纤维可重复使用且成本低廉 - 纤丝尺寸小,便于野外作业 - 与气相色谱(GC)或高效液相色谱(HPLC)仪器兼容 ## 用于气相色谱分析的[](https://www.sigmaaldrich.com)SPME纤维 传统的SPME技术用于提取和浓缩待测物,以便进行气相色谱(GC)分析。提取可通过直接浸入法(DI-SPME)进行——即将纤维直接浸入液体样品中;也可通过顶空SPME法(HS-SPME)进行——即将纤维置于样品上方的蒸气相中。 ## 用于液相色谱-质谱(LC-MS)分析的 [](https://www.sigmaaldrich.com)Supel™ BioSPME Supel™ BioSPME 是一种生物分析微量采样和样品制备技术,用于从生物样品中快速、选择性地萃取多种分析物,同时排斥不需要的大分子(如脂质、蛋白质)。后续分析通常通过液相色谱-质谱(LC-MS)进行。Supel™ BioSPME 通过直接萃取方式工作,无需样品预处理,并提供一种非穷尽的、基于平衡的萃取过程。 [![文档搜索](https://www.sigmaaldrich.com/content/dam/cms-commons/sigmaaldrich/marketing/global/images/ecommerce/document-search.png "文档搜索")](https://www.sigmaaldrich.com/documents-search) [需要更详细的信息吗?](https://www.sigmaaldrich.com/documents-search) 请访问我们的文档搜索页面,查阅数据表、证书和技术文档。 [查找文档](https://www.sigmaaldrich.com/documents-search) ## 相关文章 - [Supelco固相微萃取头选择指南](https://www.sigmaaldrich.com/SG/zh/technical-documents/technical-article/analytical-chemistry/solid-phase-microextraction/selecting-spme-fibers) 根据分析物类型和分子量推荐萃取头;各种应用的固相微萃取头选择技巧。 - [Supel™ BioSPME 96头固相微萃取装置](https://www.sigmaaldrich.com/SG/zh/technical-documents/technical-article/analytical-chemistry/solid-phase-microextraction/supel-biospme-96-pin-devices) 相对于快速平衡透析技术,Supel™ BioSPME 96头固相微萃取装置可提高血浆蛋白结合研究及其他游离分析物分析的速度和简便性,同时确保准确、可重现的LCMS结果。 - [固相微萃取:常问问题解答](https://www.sigmaaldrich.com/SG/zh/technical-documents/technical-article/analytical-chemistry/solid-phase-microextraction/faq) 与固相微萃取技术应用相关的答案和提示,以Supelco为特色 - [坚固耐用且可重现的固相微萃取(SPME)采样](https://www.sigmaaldrich.com/SG/zh/technical-documents/technical-article/analytical-chemistry/solid-phase-microextraction/nitinol-core-spme-fibers) 现在,我们推出了同样可采用Carboxen®/聚二甲基硅氧烷(CAR/PDMS)或聚二甲基硅氧烷/二乙烯基苯(PDMS/DVB)涂层的SS组件形式的镍钛合金(NIT)内核SPME萃取头。 - [Selecting the Appropriate SPME Fiber Coating –Effect of Analyte Molecular Weight and Polarity](https://www.sigmaaldrich.com/SG/en/technical-documents/technical-article/analytical-chemistry/solid-phase-microextraction/selecting-the-appropriate) Selecting the Appropriate SPME Fiber Coating –Effect of Analyte Molecular Weight and Polarity - [查看全部 (27)](https://www.sigmaaldrich.com/SG/zh/search/facet-search?focus=sitecontent&term=facet-search) ## 相关协议 - [Fast and Reliable Environmental Analysis of Aldehyde and Ketone Air Pollutants](https://www.sigmaaldrich.com/SG/en/technical-documents/protocol/analytical-chemistry/calibration-qualification-and-validation/fast-and-reliable) Aldehydes and ketones are ubiquitous air pollutants.
