XPS - K-Alpha X-Ray Photoelectron Spectrometer from Thermo Scientific

The Thermo Scientific K-Alpha is a completely integrated, monochromated small-spot X-ray Photoelectron Spectrometer (XPS) system. Advanced performance, reduced cost of ownership, increased ease of use and small size makes K-Alpha the ideal solution for a number of existing, as well as new surface analysis application areas.

K-Alpha is developed for a multi-user environment and is the first XPS tool to provide a completely automated workflow from sample entry to report generation. The Thermo Scientific K-Alpha is a fully integrated X-ray photoelectron spectrometer. The latest revision of the award winning K-Alpha XPS platform features dramatically improved spectroscopic performance, offering higher count rates, quicker analysis times and enhanced chemical detectability. Analytical options now include a tilt module for ARXPS data collection and a re-circulating inert-gas glove box for air-sensitive sample transfer.

K-Alpha has an exciting range of new software features designed to further enhance the user experience. Integrating cutting edge monochromated XPS performance with intelligent automation and intuitive control, K-Alpha features a multi-user environment to meet the requirements of both experienced XPS analysts and newcomers to the technique.
