ESA Biosciences Takes Home PITTCON Silver Editors' Award For Breakthrough Corona CAD HPLC Detector.

CHELMSFORD, Mass. -- ESA Biosciences, Inc., a subsidiary of Magellan Biosciences, Inc., has won the Silver Editors' Award at the 2005 Pittsburgh Conference and Exposition (PITTCON) for its breakthrough Corona(TM) Charged Aerosol Detector for HPLC. The Award was announced at PITTCON's annual meeting in Orlando, drawing more than one thousand exhibitors.

"We are extremely grateful and tremendously excited with this recognition," said Walter DiGiusto, ESA president. "The Award is very special because it comes from a group of editors who are attuned to the most recent advancements of technology and instrumentation in our industry. To be selected from so many competing products is indeed an honor and an affirmation that the Corona is indeed a truly universal detector that will greatly aid researchers and laboratories."

The Corona Charged Aerosol Detector offers all-in-one performance benefits that refractive index (RI), low wavelength (UV), evaporative light scattering (ELS), and chemiluminescence nitrogen (CLN) detector methods lack. Its superior performance typically provides ten times the sensitivity of ELS, a broad dynamic detection range over four orders of magnitude, more consistent response factors independent of chemical structure and full gradient capability, delivering for the first time to the HPLC market almost complete universality.

"The Corona CAD is the first new HPLC detection technology in almost two decades," noted ESA Vice President John Christensen. "With the Corona, researchers will have everything they have ever wanted, and perhaps more, in one detector."

Charged Aerosol Detection is a robust HPLC detection technology that delivers advanced capabilities of interest to every HPLC user-lab. The HPLC column eluent is nebulized and the resulting droplets are evaporated at ambient temperature producing analyte particles. A second stream of gas is positively charged as it passes a high-voltage, platinum corona wire. The charged gas collides with and transfers charges to the opposing stream of analyte particles. A negatively charged, low-voltage ion trap removes high-mobility ions while analyte particles transfer their charge to a collector. The charge transferred to the collector is in direct proportion to analyte mass.
