Statement

The samples are first scanned in BSE mode before each of the four EDX detectors takes spectra measurements on each individual pixel. The 4 EDX detectors are operated at very highcount rates and can analyse uneven surfaces with an imperfect polish. The spectra and BSE response can then be compared to a mineral database and classified according to a segmentation algorithm and set of rules defining compositional limits for each phase. Once classified, a fully rasterised image of individual phases can be exported for sample navigation and publication. TESCAN TIMA© uses 4 EDX silicon drift detectors attached to the TESCAN MIRA platform. Full details of the procedure for analysis and modes of operation are found in Hrstka et al., (2018)."
