The SRS 303 X-ray Spectrometer provides optimal excitation for all elements using a Siemens AG Rh 66 end-window tube. Analyses are automated using fully integrated sample changers with 10 or 72 positions by means of easy-to-use PC software. Additional programs for the system support fundamental parameters and semi-quantitative analysis, with comprehensive facilities for storing and processing data, as well as for integration in computer networks.
