QRSciences announces further equipment sales
PERTH, Monday 30 th

AUGUST 2004 - QRSciences Limited (QRS), the world
leader in the development of Nuclear Quadrupole Resonance (NQR) based
advanced explosive detection systems, today announces that it has sold another of its state-of-the-art explosive detection devices in the Australian marketplace.

Sydney based Advanced Security Systems has purchased the QRSciences T3-QCP device.

"Doing business with Advanced Security Systems, one of the more forward thinking specialists in the security field here in Australia and New Zealand can only help our local profile ," comments Kevin Russeth, Chief Executive Officer, QRSciences Limited. "Advanced Security Systems have clearly recognised that our NQR technology offers a significant enhancement in explosive detection and the association will undoubtedly lead to a further marked improvement in security services in this region."

The company is expected to find a ready market for QR technology amongst a client base requiring state-of-the-art next generation explosive and other
contraband detection capability.

"The QRSciences T3 -QCP is a state of the art detection device which covers some gaping holes that exist in the security market," says Sam Rahim, Managing Director of Advanced. "We are also excited about some other
product ideas that QRSciences are developing that extend beyond explosive detection and cover a range of other substances that our customers have an
interest in locating."

Advanced has offices in Sydney, Melbourne, and Brisbane and a subsidiary Advanced Building Systems in Canberra. The T3-QCP device purchased will
be deployed in Canberra ACT.

"The QR technique harnesses harmless and relatively low frequency radio waves and uses QRSciences proprietary software and hardware to identify
the chemical structure or unique fingerprint of specific molecules," adds Mr Russeth. "QRS testing has shown the technique can be as accurate as laboratory spectroscopy in identifying the presence of some explosive materials known to have been used in airline bombings and terrorist attacks in the past."
QR Sciences technology has been successfully tested by the US Transportation Security Administration (TSA) as an Advanced Technology "AT" explosive detection system. The technology has also been extensively
trialled and tested over the past four years by authorities, regulators and airports in the United States, Canada, European Union including the United Kingdom and Australia.
