Quant-XRD: Quantitative X-ray diffraction software, by Mark W Hounslow

Calculates semi-quantitative amounts of minerals in x-ray diffraction power mounts. Uses multiple peak areas (or heights) an inputs. Uses the methodology suggested by Hooten and Giorgetta (1977) and Hardy and Tucker (1988). Also detailed in Hounslow and Maher (1999). Program has uses in mineralogy and quantitative analysis of mineral magnetic extracts.

	Simplifies the calculation of semi-quantitative mineral amounts in XRD spectra.
	Interactive entering of sample data (peak heights or areas) for predefined peaks of minerals
	Need a binary mixture calibration performed on the XRD machine from which the data has been gathered
	Needs a companion dataset of peak areas, or heights or both the calibration standards and the samples from which the analysis is performed
	Standards and reference databases are DBASE III format, so are easily accessible from spreadsheet or database programs. These database files are NOT editable with Quant-XRD.
	Works under windows (NT, 95,98, 2000, XP)- self installing software.
	Extensive windows help file, and set of starter files and examples.

The above is a screen shot of the software, showing the Minerals reference database and the standards database windows open. The window in the upper right is a sample file, for some data from magnetic extracts from the Indian Ocean. In the bottom right is the calculation window, showing calculated weight percentages of minerals based on this data.

Downloads

Before downloading, please read the license agreement for using this freeware, which is applicable to both the compiled program and the source code. The compiled program is contained in a zip file, which should be first unzipped in a temporary directory, using a tool such as Winzip.

The source code, written is Microsoft Visual C++ (version 6.0), using MFC, is also available free. Before you download the source code, you should read the requirements.

If you have a problem looking at the help file (as you might with Vista or windows 7) with the program. Load the this update from Microsoft, which will install the missing help-file viewer.
