PAL SPME Arrow: The new dimension of SPME

PAL SPME Arrow The new dimension for Solid-Phase Micro Extraction SPME has become one of the most widely used extraction technologies for environmental, food and clinical analyses. It is well suited for automated sample preparation resulting in reduced time per sample, less sample manipulation and solvent consumption. However, the technology remained almost unchanged with some significant drawbacks, such as the limited mechanical stability and small phase volumes of the fibers. The PAL SPME Arrow (patent pending) is a new technology for micro-extraction, combining trace level sensitivity...

What Better SPME means Bigger surface, faster extraction. More sorption phase, superior sensitivity. Optimized geometry, greater robustness. 2 x higher sample throughput. Up to 10 x more sensitivity - wider linear range. PAL SPME Arrows last at least 2 x longer. Injector septa last at least 2 x longer. Lower running costs. Headspace Extraction Techniques Headspace (Syringe or Loop) SPME Fiber SPME Arrow Purge & Trap Immersion Extraction Techniques SPME SPME Arrow Better SPME –– Adaptation of existing SPME methods is straightforward –– PAL SPME Arrow works well for headspace and immersion...

More Volume: Up to 10x more Sensitivity The table below shows the dimension of a PAL SPME Arrow 1.5 mm (a), 1.1 mm (b) and a SPME Fiber (c) in comparison: Sorption phase surface Sorption phase volume Extraction yields for water samples containing PAHs @ 50 ng/L after 70 min. A PAL SPME Arrow 20 mm x 250 µm Carbon WR was compared to SPME fiber 10 mm x 100 µm Carbon WR immersion (Kremser et al., 2015).
