On-line Analysis of an Unknown sample.

    This menu includes several choices which allow the user to run a manual acquisition (Append) or to redo the points already saved in the file (Replace) or finally to run an automatic analysis using the stage file (Stage File). In this last mode, new analyses can added (Append) to the data base after the last point already saved in the file.

Off-line Analysis.

    The power of XMAS can be found in this menu. Analyses already stored can be re-computed at any time when necessary; for example when a standard calibration has been modified or the calculation method has been changed (Stoichiometry, Difference,...), (Ix->C) Intensity to Composition or (Ix->Ix/Istd)) Intensity to Relative Intensity. The Off-line mode can also be used to calculate the Composition from the Relative Intensity (Ix/Istd->C)) or the reverse calculation, Composition to Relative Intensity (C-> Ix/Istd)).

Display of Quantitative Results

    In both modes (On/Off), the program displays the results of each point, the user can easily access any specific point already acquired or calculated.
