New developments in SPME to simplify operation

by | May 14, 2020

Join us for this webinar comparing SPME devices and adsorbents showing the difference between classical SPME and a recently developed SPME configuration

Would you like to perfect your knowledge of solid-phase microextraction (SPME) and discover its full potential as a valuable tool for many application fields? This on-demand webinar will introduce you to a recently developed SPME configuration demonstrating its new capabilities as compared with classical SPME fibres.

Solid-phase microextraction (SPME) has gained, since its introduction in the early 90s, a routine status in today’s analytical labs. Its simplicity of operation, ease of adoption and automation on a GC instrument makes it a valuable tool for many application fields. Variations from the classical SPME fibre configuration emerged in recent times.

In this presentation we will show you and compare a recently developed SPME configuration (Arrow) with the classical SPME fibres with regards to dimensions, extraction and desorption behaviour and analytical performance. Devices with PDMS coating as well as particle phases will be discussed. A special focus is put on the performance of the different particle adsorbent materials applied for the devices, as these are often used for sensitive headspace applications, a domain of SPME. Here differences in the particle structure and properties, in particular for the carbon particles, show a significant influence on the extraction and desorption behaviour, and impact the analytical performance.

By viewing this on-demand webinar you will learn ...

  • the key differences between the classical SPME fibres and the recently developed configuration
  • the difference in analytical behaviour
  • the importance of particle structure and properties for the extraction and desorption process.
