Abstract:
Nerve agents have recently been used in battlefield operations, espionage wars, and terrorist attacks. These compounds, like some pesticides, cause organophosphate poisoning. The rapid, noncontact detection of a sarin simulant in the liquid phase has been demonstrated at the Diagnostics and Metrology Laboratory of the Italian National Agency for New Technologies, Energy and Sustainable Economic Development using laser photoacoustic spectroscopy, an infrared absorption technology. The first measurements, carried out with an experimental system based on a quantum cascade laser and developed for the assessment of food authenticity in the \"fingerprint region\", show that a detection limit of one nanolitre is within the reach of the instrument when chemometric analysis is applied.
摘要:
神经毒剂最近被用于战场作战,间谍战争,和恐怖袭击。这些化合物,像一些杀虫剂,导致有机磷中毒.快速,在意大利国家新技术局的诊断和计量实验室已经证明了在液相中沙林模拟物的非接触式检测,使用激光光声光谱技术的能源与可持续经济发展,红外吸收技术。第一次测量,使用基于量子级联激光器的实验系统进行,并开发用于评估“指纹区域”中的食品真实性,表明,当应用化学计量学分析时,仪器的检出限为1纳升。
