IN THE MASS SPECTROMETER DETECTOR Galileo's Channeltron® ion detectors are more dependable because w e gave t h e m a stable glass dynode surface. This simple one-piece c o m p o n e n t obsolètes the c o m plex metal multidynode detector using a resistive divider. The glass channel wall provides more accurate and consistent results plus reliability and stability for longlasting t r o u b l e free operation of your mass spectrometer. A w i d e selection of detectors is in stock for almost any standard spectrometer. Special mass spectrometer detectors will be designed to meet individual specifications. All are packaged for ease of installation. Write to us at Galileo Park, Sturbridge, M A 01518 or call (617) 347-9191. Ask us about our newest developments in Channeltron detectors.
