Key learning objectives
- Understand the fundamental differences between SPME, TF-SPME, and high-capacity sorptive extraction (HiSorb) regarding surface area and sensitivity.
- Learn the considerations you must take when selecting the optimal sorptive phase and extraction mode (immersive vs. headspace) for your matrix.
- Discover how analyte enrichment using a backflush, cryogen-free focusing trap can overcome the limitations of standard injection techniques.
- See how these techniques are applied to complex samples, from aroma profiling in foods to contaminant monitoring.
Information
Mastering sorptive extraction for GC–MS
For many GC–MS laboratories, sample preparation remains the biggest bottleneck. While traditional techniques like liquid–liquid extraction (LLE) and solid-phase microextraction (SPME) are well-established, they often force analysts to compromise on sensitivity, robustness, or automation capability, especially when dealing with complex matrices in food, environmental, and clinical research.
In this webinar, Rachael Szafnauer from Markes International will take a deep dive into the fundamentals and practical applications of modern sorptive extraction. She will explore how high-capacity sorptive extraction bridges the gap between exhaustive extraction and equilibrium sampling, offering a robust, complementary technique for trace-level GC–MS analysis.
You will learn how to select the right phase and extraction mechanism for your target compounds, how to optimize key parameters like temperature and agitation, and how coupling sorptive extraction with cryogen-free trap focusing can significantly boost sensitivity.
