Event Overview
Sample preparation plays a significant role in GC–MS analysis, with various approaches available to enhance analytical sensitivity and provide a more comprehensive sample profile. Understanding the science behind microextraction techniques, such as SPME and sorptive extraction, enables chemists to optimize methods for challenging matrices, thus uncovering more from your sample.
In this presentation, Professor Elia Psillakis from the Technical University of Crete explores advanced sample preparation techniques for GC–MS. She focuses on evolving microextraction methods, including SPME, thin-film SPME, SPME Arrow, vacuum-assisted SPME, and HiSorb. Professor Psillakis also discusses the fundamentals of these extraction techniques and explains how a deeper understanding of the sample preparation workflow can lead to improved qualitative and quantitative GC–MS analysis, resulting in more accurate and efficient extractions.
