Scintrex Trace Corporation was provided a research grant by Transport Canada to create a lightweight, portable, explosives screening device for use in the airport environment. Its latest model, the E3100 is used to detect commercial, military and homemade terrorist liquid and dry explosives using robust Chemilux sensors. The E3100 is able to process between 300 to 350 samples on a single charge of its battery. The device uses liminol cartridges, each of which last for approximately 2,000 samples.
