This Small Business Innovation Research Phase I project aims at developing laserphotoacoustic spectroscopy (LPAS) sensor for continuous, real-time measurements ofhazardous air pollutants (HAPs), and other air pollutants such as Carbon monoxide, nitrogenoxides, and sulfur dioxide. The intellectual merit of the activity lies in the creation of a new aoperationally simple, low cost, robust, compact, ruggedized field-deployable and affordableambient air and stationary source pollution sensor that is capable of real-time measuringmultiple pollutant and toxic compounds simultaneously. The instrument will use the newlyadvanced quantum cascade laser (QCL) or interband cascade laser (ICL) absorption toaccurately quantify multiple chemical compounds within a short period of time (~ 40 to 60seconds) with a precision of sub parts per billion.The broader/commercial impacts of this research are expected to be within numerous areasincluding: 1) Air toxic measurements, such as ambient air and stationary source pollutionmonitoring, industrial hygiene monitoring, confined space monitoring and process emissionmonitoring, etc. 2) Global atmospheric monitoring of air toxics, air pollutants, greenhouse gases,and trace species. 3) Military applications. Besides the environmental and industrial application,many other military applications including detection of Chemical Warfare Agent (CWA),explosives, TICs, can make use of the devices developed in this project. Potential customersinclude the EPA, NOAA or NASA for environmental monitoring, DoD for detection of IED(JIEDDO), the DHS for detection of explosives and scanning of luggage (TSA), etc.

该小型企业创新研究第一阶段项目旨在开发激光光声光谱 (LPAS) 传感器，用于连续、实时测量有害空气污染物 (HAP) 以及一氧化碳、氮氧化物和二氧化硫等其他空气污染物。该活动的智力优势在于创建一种操作简单、成本低廉、坚固、紧凑、坚固耐用、可现场部署且价格实惠的环境空气和固定源污染传感器，能够同时实时测量多种污染物和有毒化合物。该仪器将使用先进的量子级联激光器 (QCL) 或带间级联激光器 (ICL) 吸收，在短时间内（~ 40 至 60 秒）准确量化多种化合物，精度达到十亿分之一。这项研究的更广泛/商业影响预计将涉及多个领域，包括： 1) 空气毒性测量，例如环境空气和固定源 污染监测、工业卫生监测、密闭空间监测和过程排放监测等。2）全球大气中空气毒物、空气污染物、温室气体和痕量物种的监测。 3）军事应用。除了环境和工业应用之外，许多其他军事应用，包括化学战剂（CWA）、爆炸物、TIC 的检测，都可以利用该项目开发的设备。潜在客户包括用于环境监测的EPA、NOAA或NASA、用于检测IED的DoD（JIEDDO）、用于检测爆炸物和扫描行李的DHS（TSA）等。
