Computer-Aided X-Ray Diffraction Identification of Crystalline Mixtures in Forensic Science Investigations

CODEN: JFSCAS

Abstract

X-ray diffraction analysis of multiphase mixtures is sometimes rather painstaking and time-consuming by conventional manual identification using search manuals and the Joint Committee on Powder Diffraction Standards (JCPDS) file. This is the reason why a search match program has been developed in FORTRAN IV using a 32 kB Data General Nova 3/12 minicomputer with floppy disk storage to evaluate X-ray diffraction patterns in an on-line mode, regardless of intensities, permitting the mixture components to be determined from a compiled data file of forensically relevant substances. This paper discusses the problems of procedure, program setup, and results.
