This plugin to the NIH ImageJ program allows users to open and convert JEOL images files (X-ray maps) into TIFF or JPEG formats. The plugin can be used to effortlessly read an individual image file into ImageJ for additional image processing, or it can be used to convert an entire JEOL sample of images into either TIFF of JPEG formats in a batch process. During the image conversion process, it will also determine the proper scale of the image and display a micron marker, if the user selected this option.

JEOL supplies EDS calibration data for every element so that standardless, semi-quantitative, EDS analyses can be run. Most of these data are from pure elements. Because of this, in some circumstances, they my not produce adequate results when analyzing complex phases. As most probe operators know, many materials require standards of similar composition to the unknown in order to get good results. One solution is to replace the EDS calibration data with the user's data (see JEOL manual: EDS_OperationProgram.pdf). If a user is going to do this, they must make sure that their standard does not have any peak overlaps. If the users standard is not suitable as a primary standard, it still maybe useable as a secondary standard in coordination with this program EDS_Cal-Std_Mod. Instead of replacing the JEOL data, this program allows the user to adjust the JEOL standard data until correct results are obtained on the secondary standards.
