Reaching Perfection inMSandSEM.
"A man's reach should exceed his grasp..." Robert Browning Galileo detectors for Mass Spectrometry and Electron Microscopy. What silicon chips did for computers, Galileo high-performance detectors are doing for GC/MS, MS and SEM analysis. Whether your projects involve environmental or pharmaceutical analysis, analysis of organic compounds or general spectroscopy applications, a Galileo detector will speed sample identification while providing accurate and precise analysis.
When research projects require frequent sample analysis over a long period of time, you'll want the latest and best technology backingyou up. Galileo is the innovatorin analytical instrument detectors. If you demand high performance and are concerned about down time, rapid analysis, dynamic range and cost, insist on Galileo scientific detectors. You'll wonder how you ever got along without us.
Write us and ask how to ensure that your instruments have Galileo scientific detectors. Galileo Electro-Optics Corp. Scientific Detector Products Group P.O. Box 550, Dept. AA Sturbridge, MA 01566 (508) 347-9191
