SMART PAL SPME Arrow System

Using SPME Arrow and the PAL CTC autosampler for sample preparation, and the Rxi-624Sil MS column for analysis, we established the GC-MS optimization conditions for furan and alkylfurans in infant formula and coffee samples. The results of this experiment revealed that sample preparation using SPME Arrow is suitable for a variety of sample types containing high and low concentrations of furan and alkylfurans. Compared to using only headspace or a combination of SPME and HS, using SPME Arrow alone for sample preparation is expected to enhance productivity in food safety inspection laboratories.

Testing for volatile organic compounds (VOCs) in drinking water is widely conducted to ensure its safety. Furthermore, odor compounds such as methyl isoborneol (MIB) and geosmin are monitored as they cause unpleasant odors, making them subjects of analysis. This study aimed to develop a method that integrates the analysis techniques for VOCs and odor compounds, which are typically conducted separately, to achieve high sample throughput. Solid-phase microextraction (SPME) Arrow is a particularly useful technique as it allows for sample pretreatment and sample introduction to be performed with a single device. Additionally, SPME Arrow can be automated using a rail-type autosampler, significantly reducing the time required for sample pretreatment. In this study, we proposed a method for efficiently measuring VOCs and odor compounds in drinking water by combining a simplified sample pretreatment workflow with headspace-solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS).
