Solid Phase Microextraction (SPME) - How does it work for my samples?
This webinar offers a close insight into the operation and latest developments of automated SPME for VOCs and SVOCs by headspace, direct immersion and derivatization techniques. Key applications for food, water, environmental and forensic samples for use in every laboratory for GC/MS and LC/MS, also direct MS analysis are discussed.

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
Quantification of nitrosamines in water by automated PAL SPME-Arrow and GC/MS
A method for the quantitative analysis of a number of different N-nitrosamines from aqueous samples has been worked out.
