XAP, a program for deconvolution and analysis of complex X-ray spectra
James E. Quick, Abdul Malik Haleby
1989, Open-File Report 89-338
The X-ray analysis program (XAP) is a spectral-deconvolution program written in BASIC and specifically designed to analyze complex spectra produced by energy-dispersive X-ray analytical systems (EDS). XAP compensates for spectrometer drift, utilizes digital filtering to remove background from spectra, and solves for element abundances by least-squares, multiple-regression analysis. Rather than...
