X-Ray Fluorescence Laboratory


  1. QXAS - Quantitative X-ray Analysis System, is a DOS based software package for quantitative X-ray fluorescence analysis. It is available via a single installation file which permits the software to run under the Win9X, WinNT, Win2k, or WinXP operating systems. The zipped file contains single executable file "QXASSETUP.EXE". In order to install the QXAS software, download and unzip the file to a temporary directory and run the executable file. After completing the installation, you can run the QXAS software from the Desktop and Start Menu shortcuts. The Start Menu also includes links to the IAEA Web page, the QXAS Manual, the Z-Mean utility program, and to the QXAS Uninstaller facility.
    Note: it may happen that the file which stores the menu structure "C:\AXIL\SETUP.AX" gets corrupted. To recover the "SETUP.AX" file please over-write the corrupted file with the version stored in the“C:\AXIL\BACKUP” folder.
    The QXAS Manual can be also downloaded separately form here. To access the manual you require a Portable Document Format reader. Further assistance can be obtained by submitting your questions here.

  2. AXIL Tools (MS Windows, VB application, requires vbrun300.dll to run). Unzip the content of the file to a separate directory and run the different programmes independently. The included "info.txt" file explains the purpose of the different programmes. To obtain support please send an e-mail here.

  3. TXRF calculator (Excel worksheet). In order to run enable macros in your Excel. The worksheet performs calculations of element concentrations, including uncertainty budget estimation, based on data obtained from TXRF measurements. Input data format is compatible with QXAS/AXIL system. Further details and support can be obtained here.

  4. Fundamental Parameter Calculator (DOS). Unzip and run the executable file. The fundamental parameter data are stored in the executable file. For obtaining support please send your e-mail here.

  5. Excitation Spectrum Calculator (DOS). Unzip and run the executable file. The programme will output the calculated excitation spectra to an ASCII file "SPECTRUM.DAT". To obtain support please send your question here.

  6. WinQXAS - Quantitative X-ray Analysis System for MS Windows operating systems. Contains only a subset of functions available in the DOS QXAS package, namely: X-ray spectra fitting module (AXIL) and simple quantitative analysis procedure. If you need assistance, please submit your question here.

  7. A-BAT Questionnaire - updated questionnaire forms and an information letter for the Database for Accelerator-based Analytical Techniques (A-BAT). Dear accelerator user, please download the file, fill in the included questionnaire (preferably the MS Excel worksheet) and send it back as an e-mail attachment to the database custodian.

  8. Database of Reference Materials (MS Excel workbook + the data exported to ASCII text file) containing searchable database of Reference Materials (RM) and Certified Reference Materials (CRM). The workbook is supported under Microsoft® Excel 2002 (v.10) and above and will not function on lower versions of MS Office. The particular set of materials compiled in this database was selected considering typical needs of X-ray fluorescence (XRF) analytical laboratories. The database can be used as a tool to assist analysts in selecting suitable RMs/CRMs for validation of the applied analytical procedures to ensure the quality of analytical results. The database contains information on over 5600 RMs and CRMs compiled from existing sources available on the Internet (as of September 2005). The IAEA maintains also a Web-searchable Database of Natural Matrix Reference Materials containing a wide selection of RMs/CRMs not specifically focused on XRF technique. E-mails with questions related to the Database and request for assistance should be sent here.


The software, which is made available for download, the copyright in which is with the IAEA, has been developed by the IAEA to support the X-ray fluorescence analysis and is made available free of charge. The IAEA will accept no liability in the event that the software does not fully meet your requirements.
