Abstract:
:An overview on the status and function of current spectrometry hardware, of detectors having energy-dispersive (spectrometric) properties as well as of the latest developments in quantitative spectrometry software is presented. Making extensive use of modern computing power, new strategies in high-precision spectrum analysis have been developed which enhance the quality of results and also open new fields of spectrometric applications. Three principles have been newly introduced to spectrum analysis software:
