General Description
The LISA® Manportable system has been developed as part of the DHS S&T Low Vapor Pressure Chemical Detection Systems (LVPCDS) program. The system provides a capability to perform real-time sensitive site assessment (e.g., inspect buildings, roadside formations, equipment, vehicles, aircraft, and other manmade or natural surfaces) for the presence of low vapor pressure chemicals, other persistent chemical agents, and TICs, with the expanded capability to include explosives, homemade explosives and their precursors.
