A BASIC-language program for dedicated energy-dispersive microanalysis of thin samples in TEM or STEM

The program QTHIN combines those methods for processing energy-dispersive X-ray spectra and computing concentrations best suited to thin section microanalysis in TEM or STEM. The program is in BASIC, and so can be modified (for instance for unusual geometries, other matrices such as oxides, etc.). It is suitable for routine use on complex samples with peak overlaps, and for "not-so-thin" samples in which absorption is not negligible.
