WILMINGTON, MA--(Marketwire - Oct 27, 2011) - Implant Sciences Corporation (OTCQB: [ IMSC ]) (PINKSHEETS: [ IMSC ]), a high technology supplier of systems and sensors for homeland security markets, today announced sales of its Quantum Sniffer™ QS-H150 portable explosives trace detection devices to two new customers in Europe. Units have been sold for deployment in the protection of a major European bank and for use in training at an international explosives ordinance disposal (EOD) school.

It has already been deployed in places such as stock exchanges, hotels, and federal facilities. It is a testament to the quality of both our product and our distributors that such a wide range of customers can appreciate the value of our explosives trace detectors," stated Glenn D.
