环境有毒气体实时监测

CUSTOMER PROBLEM：Many possible terrorist threats have been identified by the Department of Homeland Security, among which is the use of Toxic Industrial Chemicals (TICs) to either harm building occupants or cause business disruptions. In order to maintain a level of security for populated buildings, a continuous air monitoring system should be employed in the building air handling systems or at entrances, mail rooms, and shipping docks. Initial systems deployed for TIC detection used monitoring technologies which have been found to lack the sensitivity or selectivity to make them useful against multiple chemical threat sources in the presence of interferents such as common solvents and cleaners. These interferents have often resulted in a large number of false alarms which are costly and reduce the overall customer satisfaction with the monitoring system. An analyzer that can detect multiple agents very quickly with no, or extremely infrequent, false alarms will enhance the utility and security protection offered by these ambient air monitors for homeland security applications.
