Micromethods: Automated µSPE & SPME

In the modern analytical laboratory, "micromethods" are rapidly moving from a niche concept to an essential strategy. These techniques are transforming sample preparation by fundamentally miniaturizing the process. This shift not only aligns with the principles of Green Analytical Chemistry (GAC) by drastically cutting down on solvent and sorbent consumption, but it also directly boosts laboratory efficiency, reduces manual variability, and improves data quality. To explore the practical benefits of these advanced approaches, we are hosting a special two-part webinar series.

Session 1: Modern SPME Geometries for Ultra-Trace Contaminants

Guest Speaker: Madison L. Williams, University at Buffalo

We are honored to host Madison L. Williams, a Ph.D. candidate at the University at Buffalo, as our guest speaker.

She will discuss her recent publication focusing on:

• A direct performance comparison of SPME Fiber vs. SPME Arrow for volatile (FTOHs) and semi-volatile (MeFOSE) PFAS.
• How the extraction mode (Headspace vs. Direct Immersion) and agitation mode affect extraction efficiency.
• The broad range of applications that can be tackled with SPME.

Session 2: Automated µSPE for QuEChERS Analysis

Speaker: Dr. Hagen M. Gegner, CTC Analytics AG

The QuEChERS method is a global standard for pesticide analysis in food, but the manual dispersive SPE (dSPE) cleanup step is a well-known bottleneck. This step is labor-intensive, introduces variability, and often struggles with high-matrix samples like fats, oils, and pigmented spices. These "dirty" extracts lead directly to matrix effects and costly, frequent instrument maintenance. This webinar explores a "walk-away" solution using automated Micro Solid Phase Extraction (µSPE) cartridges. We will show how this automated, miniaturized workflow:

• Provides a superior, more reproducible cleanup than manual dSPE.
• Reduces solvent and sorbent consumption using miniaturized cartridges.
