SHIMADZU CORPORATION AND ACD/LABS BRING TOGETHER ACD/LABS' MS SOFTWARE TOOLS WITH SHIMADZU LC/MS SYSTEMS

Toronto, Canada, (June 6, 2005) -- Shimadzu Corporation and Advanced Chemistry Development, Inc., (ACD/Labs) have agreed to integrate ACD/Labs' MS software tools for metabolite identification together with Shimadzu Corporation's high mass accuracy MSn data. This collaboration will allow researchers to visualize and interpret mass spectrometry fragmentation data and chromatography data with targeted chemical structures.

Kozo Shimazu, Corporate Officer, Deputy General Manager for Mass Spectrometry, states, "As part of our on-going development to support metabolite identification research, with the added value of high mass accuracy MSn data generated by our LCMS-IT-TOF systems, we believe this collaboration will help investigators in identifying metabolites with greater certainty, quickly."

Research groups using Shimadzu Corporation's unique LCMS-IT-TOF technology will be able to link directly with ACD/Labs MS software tools to identify related metabolite products using high mass accuracy MS data and chemical structure information.

Dr Mark Bayliss, Director of Analytical Informatics for ACD/Labs, adds, "ACD/Labs continues to explore and develop new opportunities for metabolite identification and our collaboration with Shimadzu Corporation is a significant global business opportunity."
