"ELECTRON SPECTROMETERS

In 1970, AEI introduced their first electron spectrometer, the ES100. It was the first commercially-available instrument to combine successfully three operating techniques' these being high and low energy photo-electron spectrometry and Auger spectrometry. The wide range of possible applications included catalysis study, corrosion research, structural organic chemistry and ceramics technology. The versatility of the ES100 was increased further by the incorporation of several sample handling facilities, together with ultra-violet and electron bombardment sources. This product proved to be a highly successful venture, out-selling all of its competitors.

The following year, the ES200 was announced. This spectrometer was a modification of, and a successor to, the ES100. In addition to the features of its predecessor, the ES200 sample region is designed for UHV applications, a pressure of 10^-10 torr being attainable in the source. Sample excitation using monochromatic X-rays is now available thus increasing resolution and minimizing interference. To date approximately 40 of these instruments have been sold.

Accessories available for AEI electron spectrometers include a monochromator, an extremely versatile data system, sample handling and introduction systems, and a multiple collector."
