采用Ekspla独具特色的PGX11系列窄线宽皮秒光学参量发生器,利用激光吸收光谱学检测原理,检测人呼吸气体中的疾病标识物。
Number of trace compounds (called biomarkers), which occur in human breath, provide an information about individual feature
of the body, as well as on the state of its health. In this paper we present the results of experiments about detection of certain
biomarkers using laser absorption spectroscopy methods of high sensitivity. For NO, OCS, C2H6, NH3, CH4, CO and CO(CH3)2
an analysis of the absorption spectra was performed. The influence of interferents contained in exhaled air was considered. Opti−
mal wavelengths of the detection were found and the solutions of the sensors, as well as the obtained results were presented. For
majority of the compounds mentioned above the detection limits applicable for medicine were achieved. The experiments showed
that the selected optoelectronic techniques can be applied for screening devices providing early diseases detection.
