固相微萃取(SPME)是一种通用的、无溶剂样品制备技术。其利用吸附/吸收和解吸作用，通过萃取相包覆的纤维头浓缩样品中的分析物。这一技术将分析物采样、分离和富集处理融合在一个步骤之中。SPME广泛用于环境挥发物、食品饮料、香精香料、法医学、毒理学以及制药样品采样。
智能SPME纤维头
智能SPME纤维头是我们的创新产品，传统涂层结合含有智能芯片的手柄有助于实现准确、可靠、一致的结果。我们的智能萃取头包括Carboxen®萃取头、两相涂层萃取头、或多相涂层萃取头，配有智能芯片，除可提供无缝样品制备转移外，还可提供以下其他优势：
可追溯性，以便检查使用情况、进样数、操作日期和接触温度
高通量样品制备
针对每种涂层萃取头，自动应用正确的参数
了解更多信息关于用于自动化采样的智能SPME纤维头。
镍钛合金内核SPME纤维头
镍钛合金内核SPME萃取头增强了萃取性能，并提高了色谱结果精度。镍钛合金内核萃取头现可选择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。镍钛诺芯纤维头的其他优势包括：
批次间和批次内更好的重现性
更高的萃取头耐用性
与熔融石英内核萃取头相近的选择性和惰性
了解更多关于镍钛合金内核SPME纤维头的信息。
外包覆（OC）SPME纤维头
纤维头外包覆是一种新型的纤维包覆技术，用于保护SPME纤维头免受基质成分的影响。它可实现将纤维头直接浸入到复杂样品中，确保更有效的萃取（例如半挥发性化合物）。聚二甲基硅氧烷（PDMS）用于外包覆PDMS/二乙烯基苯（DVB）纤维。所得到的纤维具有更加坚固的物理性质，并可耐受化学污染以及有效的洗涤步骤以去除粘附的基质。

BioSPME
与目前用于血浆蛋白结合研究和其他游离分析物分析的生物分析样品制备技术相比，BioSPME技术更加简单快速。Supel™ BioSPME设备的主要优点包括：
比基于快速平衡透析的方法快3倍
通用的96针头形式，可与标准耗材兼容
工作流程简单，适用于完全自动化或手动操作
