How many mass spectrometers can your laboratory afford? Only one? Good. Call us. We make only one basic model of mass spectrometer. But it's a mass spectrometer that does many, many things. From the analysis of gases to the analysis of high-temperature solids, with sensitivities for sub-microgram quantities. How did we manage to pack such broadband capabilities and high sensitivity into a single instrument? By engineering the design to the users' many needs. And by incorporating the latest developments in ultra-high vacuum technology. Our instrument includes such features as ion pumping for lower pressures and a cleaner system; an electron bombardment source with an ambient or heated gas inlet system; gas
chromatograph marriage with the appropriate separator; high temperature Knudsen cell; surface ionization source. The completely quick-change design of the instrument also features adjustable and positionable slits on sources and collector; Faraday cup collector and electron multiplier with graphic recording or high-speed oscillograph; multi-adjustable magnetic scanning; high-stability precision electronics. And above all—ease of operation. If your interest is more than academic, write or call (918) 437-1776 for our comprehensive brochure.
