CalcZAF and Standard Modeling Utilities for SEM/EPMA

CalcZAF is intended for calculations on unknown compositions (k-ratios and matrix corrections), while Standard performs calculations on known compositions (searching, matching, modeling).

CalcZAF and Standard are excellent off-line EPMA calculation utilities for both teaching and research.

CalcZAF: Modeling Unknown Compositions

CalcZAF is a FREE modeling/calculation utility for SEM/EPMA that includes calculation of ZAF and Phi-Rho-Z matrix correction parameters from arbitrary compositions with 11 different analytical models to choose from and compare, and 6 different mass absorption coefficient tables for a total of 66 different quantitative options.

To install CalcZAF and Standard simply download the CalcZAF.msi file using the button below and double click the installer. The setup wizard will take you through the installation process. PENEPMA 2012 is automatically installed by the installer.

Once installed on your computer, CalcZAF and Standard can be automatically updated to the latest available version simply by using the Help | Update CalcZAF menu.

  • CalcZAF accepts compositions to calculate intensities or calculates composition from intensities using normalized k-ratios, raw k-ratios or unknown and standard counts.
  • CalcZAF calculates binary compositional and empirical intensity datasets for plotting error histograms to evaluate matrix methods.
  • CalcZAF applies geometric corrections to intensities for particles (cubes, prisms, spheres and fibers) and thin films based on various adjustable parameters.
  • CalcZAF has powerful tools for calculating detection limits and x-ray and electron transmission ranges in compounds.
  • CalcZAF also supports fast Monte Carlo calculations using polynomial alpha factors derived from PENEPMA Monte Carlo k-ratio calculations. These alpha factor parameters provide high speed Monte Carlo calculations for arbitrary compositions.

Additional CalcZAF Features

Standard: Modeling Known Compositions

The CalcZAF download also includes our Standard application, a compositional database utility for modeling analytical calculations and Monte Carlo electron-solid effects.

  • Use Standard for modeling of known compositions with an easy to use Graphical User Interface (GUI) for PENEPMA and PENFLUOR/FANAL for fast modeling of secondary fluorescence from boundary phases.
  • Standard includes several composition reference databases (NIST, Deere, Howie and Zussman, Dana’s ore minerals).
  • Standard is a full featured compositional database utility with k-factor, matrix, backscatter and x-ray intensity modeling.
