BOSTON–Sept. 5, 2006–PerkinElmer, Inc. (NYSE: PKI), a global leader in Health Sciences and Photonics, today announced the acquisition of Avalon Instruments Limited, based in Belfast, Northern Ireland. The acquisition expands and complements PerkinElmer’s Molecular Spectroscopy product portfolio through adding a family of innovative bench-top dispersive Raman spectrometers. The Avalon Raman platforms support both bulk analysis and microscopic imaging, enabling scientists and technicians to gain more information about their samples with excellent reproducibility. Terms of the deal were not disclosed. Raman spectroscopy identifies and characterizes the composition of both organic and inorganic materials in a wide range of applications. It is a complementary analysis technique to near infrared spectroscopy (NIR) and infrared spectroscopy (IR). Raman provides labs with the ability to analyze solids, liquids, powders, gels, slurries and aqueous solutions in bulk or to address variation in sample distribution with imaging. The technology is applicable to a diverse range of end markets, including pharmaceuticals, forensics and academia. “Customers will now have a single dependable source for high-throughput IR, NIR and Raman, along with integrated software and accessories,” said Robert F. Friel, president of PerkinElmer Life and Analytical Sciences. “The PerkinElmer Raman instrumentation is designed for intuitive use, minimal operator intervention, and highly reproducible results to help labs achieve a high level of throughput and productivity.” “We are excited to join PerkinElmer and contribute to their innovative approach to product development and continuous improvement, along with becoming part of a global leader in customer service and support,” said Dr. Andrew Dennis, managing director, Avalon Instruments.
