[Analysis Case] Evaluation of Odor Components in Essential Oils

[Analysis Case] Evaluation of Odor Components in Essential Oils

Concentration analysis of odor components using solid-phase microextraction (SPME).

The concentration of volatile components that humans perceive as odors can be very low, and they may not be detectable using the conventional HS (Headspace) method for GC/MS measurements used for analyzing volatile components. By using Solid-Phase Micro Extraction (SPME), it becomes possible to concentrate the volatile components and introduce them into GC/MS, allowing for the detection of many trace components. This document presents a case study analyzing odor components in trace amounts of essential oils.

[Technical Data] High-Precision Analysis of Volatile Organic Compounds and Odor Compounds in Drinking Water

[Technical Data] High-Precision Analysis of Volatile Organic Compounds and Odor Compounds in Drinking Water

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).
