If 'always symbols' has been chosen, are all entered atomic numbers automatically converted into element symbols.

This panel is functionally identical to the usual function for specimen load.ī) Element symbols, and atomic numbers can be entered, even as mixed. If there are samples stored, then an additional button appears with the symbol of file store cabinet. A name for this composition is to select to use for a later re-load. There are new features of the spectra popup menu presentation and also a new pop-up menu of the Composer window:Ī) Created compositions of samples can be saved for later use. Please take in mind the always different analysis depths in connection with expected homogenousity of specimen. With this a procedural instruction is given, which line series of specimen in regard of conditions are the best choices. An other check-box (best MDL) makes permanent dynamical selection of the line series with best detection limits for each element. With selecting a check-box (Uo), the overvoltages for all elements are displayed (incidence electron energy Eo /critical electron energy Ec for different electron shells). Often it is very obvious, the X-rays of different elements in a spectrum are from very different specimen depths. The selection of optimal line series is possible before time-consuming data acquisition with variation of possible analytical conditions in spectra simulation. Therefore it is possible to select optimum line series in regard of analytical tasks for each element. The values are displayed always separated for K-, L- and M-radiation (if excitation is possible). Therefore the absorption limits the analysis depth in many cases. Low energy X-rays are possible to excite in depth, but is very often not able to leave the specimen. For analysis depth also absorption of low energy X-rays is considered. Please take in mind, this is also an estimation but all values are very helpful in comparison between the elements, used line series or between different analytical conditions. The maximum emission depth of measured X-rays are displayed and sorted with all specimen elements. With this tool, minimum detection limits for all elements of specimen are easy to estimate in regard to analytical conditions.

Now there is also a computation of detection limits and analysis depths for the Composer, like this was with the one- and two-element simulation in previous versions: For a maximum comfort the used elements and concentrations are always saved for later program runs. The spectra composer was extended for a specimen with up to 30 elements.
