New Device To Complement Smiths Detection HazMatID Analyzers in theentification of Unknown Liquids, Powders and Solids; Highly Accurate Analysis of Unidentified Substances

DANBURY, C.T., March 17, 2005 - Smiths Detection, the world's leading provider of detection equipment, has formed a strategic partnership with DeltaNu to introduce a hand-held Raman spectroscopy system that will be used toentify unknown chemical substances.  The new system is designed to complement Smiths Detection's widely deployed HazMatID FT-IR system and offers a confirming, independent analysis of unidentified liquids, powders and solids.  The new system will be available for sale to emergency responders in the summer of 2005.

Based on Raman technology, the new chemical analyzer willentify toxic industrial chemicals, nerve and blister agents, weapons of mass destruction, explosives, narcotics, and common chemicals in seconds.  The system will non-destructively analyze substances directly or through glass and clear plastic containers.

"To verify theentification of a potentially dangerous unknown substance, emergency response teams routinely conduct two or more independent tests," said Jim Fitzpatrick, Smiths Detection General Manager for Emergency Responders.  "Raman spectroscopy, when combined with FT-IR spectroscopy, enables first responders to quickly apply two fundamentally different techniques to a sample and thereby ensure a high degree of accuracy whenentifying unknowns."

"We are pleased to partner with Smiths Detection," said Dr. Keith Carron, CEO of DeltaNu. "Our hand-held Raman technology is a vital, new addition to the arsenal of tools enabling first responders to rapidlyentify unknown chemicals at the site of the incident. Our company has been looking for the appropriate strategic partner to take our revolutionary technology to market and Smiths was at the top of our list."

Smiths Detection said the combination of the two analyzer technologies is particularly well suited toentifying complex materials such as mixtures containing multiple chemicals and wet samples.

The DeltaNu Raman system creates a unique spectral signature by measuring the interaction of a low-power laser with a sample. Like the HazMatID, the signature is compared against an on-board database library of known chemicals for anentity.  Because Raman measures a completely different behavior than the HazMatID, it is aneal confirmatory tool for the analysis of unknowns.

Smiths Detection has sold hundreds of its popular HazMatID systems to Fire Department HazMat Teams, Law Enforcement, Military, and a variety of federal agencies including the FBI, DEA, US Customs, and UN Weapons inspection teams.  The HazMatID is a tool that measures the way chemical samples interact with infrared light, with each substance generating a unique "infrared fingerprint."  The HazMatID instantly compares the infrared fingerprint against a database to provide theentity of the unknown.

About DeltaNu DeltaNu, LLC, a Laramie, Wyoming-based company, was founded in 1997 by two University of Wyoming chemistry professors and a seasoned technology entrepreneur. The company's Raman technology was developed using nearly $4 million in seed capital grants received from the federal Small Business Innovation Research (SBIR) program. In addition to the Raman system designed for Smiths Detection, the company manufactures and sells a number of other Raman systems for the research, education, industrial and forensic markets.
