According to studies showing that volatile organic compounds (VOCs) from human breath gas can provide biomarkers for human disease, especially for lung cancer [1], a non-invasive method was developed to measure the exhaled air from cancer patients using chromatography-mass spectrometry (GC-MS). However, traditional GC-MS equipment is very expensive and requires specialists to operate. In this research we demonstrate a portable micro gas chromatography (μGC) system to overcome the limitations of conventional methods and realize small chips for big data. ? 2015 IEEE. |
