Prosolia Announces the Launch of
Omni Spray™ Ion Sources

Indianapolis, May 24, 2005—Prosolia, Inc. has announced the launch of the first product in its line of Omni Spray™ Ion Sources. These revolutionary ion sources are based on the Desorption Electrospray Ionization (DESI) technique from the laboratory of Dr. R. Graham Cooks, Purdue University, West Lafayette, Indiana. The technology is simple, sensitive, gentle, and versatile. This proprietary technology allows mass spectra to be obtained almost anywhere under ambient conditions, directly from inert surfaces or even directly from living tissues, with absolutely no sample preparation. Omni Spray™ Ion Sources will officially be introduced at the 53rd American Society for Mass Spectrometry (ASMS) Convention in San Antonio, June 5-9, 2005.

Dr. John Campbell, President and CEO of Prosolia, stated, “The DESI technology has already generated considerable interest within the mass spectrometry community and upon full commercialization will revolutionize the field of mass spectrometry. The launch of our line of Omni Spray™ Ion Sources will change what mass spectrometers can do, where mass spectrometers are used and even who uses them. The Omni Spray™ Ion Sources will be offered in user friendly configurations, allowing researchers to easily install them on most commercially available mass spectrometers and immediately begin generating meaningful data.”
