from: EDAX the innovators .. . "to get you all the information from your SEM/TEM x-ray analysis" EDAX/EDIT®

systems provide. . .

'Optimized qualitative analysis - removal of background and peak overlaps without requiring a library of standards. - no need to prejudge what elements are present. 'Automatic semiquantitative analysis - single pushbutton listing of all statistically significant peaks. True net intensities allow direct comparisons. 'Quantitative analysis with or without standards - major breakthroughs in theory handle irregular surfaces normally encountered in SEMs. - traditional probe standards, or others, or none at all can be used. - special models developed for thin sections, organics, etc. VS:

'Computing power for your lab - utilize standard high-level languages (Basic, Fortran, Algol, etc.).

- perform general purpose functions while you take x-ray data. - extensive program libraries. 'Again, a new industry standard from EDAX - 4th generation EDAX software shows the continued innovation that has made us the leader since the beginning. - utilizes microprocessor chips, the latest development in computer technology.
