Headspace Solid-Phase Microextraction/Gas Chromatography-Mass Spectrometry for the Determination of 2-Nonenal and Its Application to Body Odor Analysis.

ABSTRACT: The odors and emanations released from the human body can provide important information about the health status of individuals and the presence or absence of diseases. Since these components often emanate from the body surface in very small quantities, a simple sampling and sensitive analytical method is required. In this study, we developed a non-invasive analytical method for the measurement of the body odor component 2-nonenal by headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry by selective ion monitoring. Using a StableFlex PDMS/DVB fiber, 2-nonenal was efficiently extracted and enriched by fiber exposition at 50 °C for 45 min and was separated within 10 min using a DB-1 capillary column. Body odor sample was easily collected by gauze wiping. The
