"Canine explosive detector dogs are excellent tools for patrol, however, they do have a significant rate of false alarm, meaning they will signal a false alert," says Sean Moore, vice president of sales and marketing at HiEnergy Technologies.

"Where a device such as the Sigma 3E3 is extraordinarily useful is in bridging the gap between the first-responding canine and the step in which a bomb squad is actually called to respond," he adds.

The Siegma 3E3 is a mobile, suitcase-borne explosive detection and confirmation system, incorporating HiEnergy's proprietary Atometry technology. It is said to be unique in that it can detect and confirm whether an object or container carries a select group of dangerous or illicit substances, such as explosives, biological agents, or illicit drugs, with a probability of detection equal to approximately 97.75%, and "false negative" and "false positive" rates of nearly 2.25%. Combined with its mobility and stand-off design, the Siegma 3E3 is particularly well-suited for the detection of terrorist-made bombs or improvised explosive devices (IEDs). The system not only detects, but also identifies the explosive and/or other substance. The basis of its technology is 'Atometry,' which means the ability to decipher an empirical chemical formula, or specifically, the ability to detect and identify explosives at the chemical, molecular or empirical level. In addition, the Sigma 3E3 has the ability to determine the mass amount, which means it would come back with a 98% probability that there is an explosive there, identify the explosive by name, and how much it weighs. Knowing the weight is crucial because it enables deciding whether to simply cordon off an area or evacuate an entire facility. Unlike military ordnance, IEDs are unconventional in their delivery, often inaccessible by vehicle-borne systems, and contain non-standard mixtures that require chemical formula identification not obtained by the common "anomaly" and chemically "blind" detectors currently in the marketplace.
