SPME: 固相微萃取
SPME: 固相微萃取

固相微萃取是一种非常有效的自动化样品制备方法

固相微萃取是一种非常流行的无溶剂和真正的绿色分析萃取技术。可以进行顶空相萃取,也可以做液体中浸入式萃取。在痕量分析实验室已经使用了25年的时间里,已经开发出了丰富的应用文献库

固相微萃取法
  • PAL System提供传统的SPME Fiber以及新开发的更灵敏的SPME Arrow技术。

  • SPME Arrow非常坚固,可提供更高的吸附剂体积和表面。使用SPME Arrow速度更快、灵敏度更高。

  • 这两种技术都使用搅拌器进行孵化,Arrow也使用一个加热装置,用于磁力搅拌样品瓶。

  • 极性分析物的纤维头上衍生用于GC分析也可以整合进自动化工作流程中。

  • 极性分析物的浸入式提取和在纤维头上衍生用于GC或LC分析也可以整合进自动化工作流程中。

  • SPME取样只需要几克或几毫升的少量样品。

  • 使用流通池可实现在线分析。

Flavor and Off-Flavor Analysis using Solid Phase Microextraction

Solid Phase Micro-Extraction (SPME) is widely used for chemical analysis of foods, beverages and food contact materials. As an automated technique, the SPME applications are selected for their simplicity, throughput and extraction efficiency.  As a solvent-free extraction, it is gains even more importance today as a green analytic technique. Besides the traditional SPME Fiber, the new SPME Arrow is enhancing trace level sensitivity at high mechanical robustness. With these features, this presentation will give insight on SPME analysis in coffee, wine and off-flavors.

Determination of C2-C12 aldehydes in water by SPME Arrow on-fiber derivatization and GC/MS

The method employing a SPME Arrow allows for the quantitation of water samples down to 50 ng/L for most of the described aldehydes with good precision.
A previous publication applying traditional standard SPME fibers and GC/MS achieved sensitivities down to 120-340 ng/L in spiked samples for C1, C3-C5
