Thermo Scientific K-Alpha is a fully integrated, monochromated small-spot X-ray Photoelectron Spectrometer (XPS) system. K-Alpha is designed for a multi-user environment and is the first XPS tool to deliver a fully automated workflow from sample entry to report generation. The latest revision of the K-Alpha platform features dramatically improved spectroscopic performance, delivering higher count rates, 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. Combining 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.
