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
Determination of contaminating fragrances in fish by PAL SPME Arrow and GC-MS/MS
A method for the quantitative analysis of 9 polycyclic and nitro musk fragrances from fish samples by PAL SPME Arrow and GC-MS/MS has been developed.
Enhanced Method Development Capabilities with Automated SPME Extraction Optimization
A workflow is described that enables the automated selection of the most suitable extraction conditions (type of fiber, extraction time and temperature) for the GC/MS analysis of a number of contaminants in oil and water samples.
Comparison of PAL SPME Fibers with established Fibers
The performance of SPME fibers is an essential aspect of an analytical method. This study shows the comparison of three different SPME fibers of a conventional brand and the new PAL SPME Fibers.
Automated Sample Preperation for LC-MS and GC-MS -Solutions for Food and Environmental Analysis
In this presentation we want to discuss an important development and a demand from analytical laboratories about the standardization and the automation of sample preparation procedures for food safety, environmental, the forensic or pharmaceutical analysis.

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.
