Volatile organic compounds (VOCs) released by humans through their skin were investigated in near real time using ion mobility spectrometry after gas chromatographic separation with a short multi-capillary column. VOCs typically found in a small nitrogen flow covering the skin are 3-methyl-2-butenal, 6-methylhept-5-en-2-one, sec-butyl acetate, benzaldehyde, octanal, 2-ethylhexanol, nonanal and decanal at volume fractions in the low part per billion-(ppb) range. The technique presented here may contribute to elucidating some physiological processes occurring in the human skin.
使用离子迁移谱仪，在短的多毛细管柱气相色谱分离后，对人体皮肤散发的挥发性有机化合物（VOCs）进行了近实时研究。氮气覆盖皮肤时，通常会发现一些 VOCs，如 3-甲基-2-丁烯醛、6-甲基庚-5-烯-2-酮、仲丁基乙酸酯、苯甲醛、辛醛、2-乙基己醇、壬醛和癸醛，其体积分数在低 ppm 范围内。本文介绍的技术可能有助于阐明人体皮肤发生的某些生理过程。
