XEI Scientific Celebrates its Silver Anniversary

Join us in celebrating 25 years of continuing progress in fighting hydrocarbon contamination with Evactron® plasma cleaners.

Ronald Vane, XEI's President and Founder

I started XEI in 1991 to fight SEM contamination and I have been stopping dirty pictures ever since. In 1999 I invented the Evactron, the first commercial in-situ plasma cleaner designed for use on an electron microscope. It is the single accessory that you can buy to improve instrument performance, and it enables advanced technologies in FIBs and SEMs equipped with turbo-molecular pumps. Any analytical techniques that need to be carbon-free, such as EELS, low energy EDS, EBSD, BSD, as well as biological techniques including CLEM, 3D imaging, cryo-applications and low voltage FESEM, are made possible by Evactron cleaning. Routine microscope service visits should include plasma cleaning as a final step to a pristine vacuum environment. Evactron Decontaminators at this year's M&M 2016 conference were a mainstream FIB/SEM accessory to be purchased with new electron microscopes or after market.

Ronald Vane, XEI president and founder

XEI Scientific Inc. invented the Evactron De-Contaminator in 1999 as the first plasma cleaner to use a downstream cleaning process to remove carbon from electron microscopes. A proprietary plasma source uses air to produce oxygen radicals for oxidation of carbon compounds for removal by the pumps.

Carbon-free-vacuum produces the highest quality images and analytical results from SEMs and other vacuum analytical instruments. XEI innovations also include a unique RF plasma generator, a patented RF electrode, and easy start programmed plasma cleaning. All XEI products come with a 5 year limited warranty and are compliant with CE, NRTL, and Semi-S2 safety standards.

XEI offers a variety of Evactron® decontamination systems to meet customer needs at >2400 installations around the world. For more information on products and services offered by XEI Scientific, Inc., see
