The PulseTor EMSAviewer allows you to measure peak areas and resolutions easily, and shows the pile-up performance of your system by reporting the Pulse Pair Resolving Times (PPRTs) for different pairs of peaks.

EMSAviewer is not a full EDS software package. In particular, it does not perform quantitative analysis, it does not identify elements automatically, and its background models are empirical and rudimentary. It is a manual tool for peak and pile-up measurement.

EMSAviewer is written in the Java language, and will operate on Windows, Mac and Linux platforms equally well. It should load most variations of the EMSA text format for spectra, which is exported by most EDS systems. There is also one demonstration spectrum supplied (RaneyNiDemo.msa).

EMSAviewer was developed entirely by our student intern for the past two summers, Owen Healy, who will be entering Rutgers University in the fall of 2008. We think it's pretty impressive work for a high school senior who had never heard of EDS prior to June 2007.
