K-Alpha

The Thermo Scientific K-Alpha is a fully integrated X-ray photoelectron spectrometer. The latest revision of the award winning K-Alpha platform features dramatically improved spectroscopic performance, delivering higher countrates, faster analysis times and improved chemical detectability. Analytical options now include a tilt module for ARXPS data collection and a recirculating inert-gas glove box for transfer of air-sensitive samples. K-Alpha comes with an exciting range of new software features designed to further enhance the user experience. Combining cutting edge monochromated XPS performance with intelligent automation and intuitive control, K-Alpha is designed for a multi-user environment to meet the requirements of both experienced XPS analysts and newcomers to the technique.
