"High-Precision Analysis of Volatile Organic Compounds and Odor Compounds in Drinking Water Using HS-SPME Arrow-GC-MS" #Technical Document #Application Note

High-Precision Analysis of Volatile Organic Compounds and Odor Compounds in Drinking Water by HS-SPME Arrow-GC-MS

Testing for volatile organic compounds (VOCs) in drinking water is widely conducted to ensure its safety. Furthermore, odor substances 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 substances, 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 that efficiently measures VOCs and odor substances in drinking water by combining a simplified sample pretreatment workflow with headspace-solid-phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS).

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
