Abstract

This study investigated the volatile organic compounds (VOCs) in human skin gas and standard gas using modified gas chromatographic system. It devised sampling glass syringe temperature at 25°C or heating 80°C prior to injecting sampling gas into a gas chromatograph. The peak area of 6-methyl-5-hepten-2-one at 50, 100, and 250 ppb heated at 80°C was 337, 236, and 214% higher than that at 25°C, respectively. The peak area of hexanal at 50, 100, and 250 ppb heated at 80°C was 164, 159, and 135% higher than that heated at 25°C, respectively. Likewise, the peak area of acetone at 50, 100, and 250 ppb heated at 80°C was 115, 116, and 109% higher than that heated at 25°C, respectively. These results suggest that a higher VOC peak area can be obtained by heating the sampling glass syringe before injection into the gas chromatograph.
