Instrument and Sample Contributions to the Peak Profile must be Deconvoluted In order to analyze crystallite size and microstrain in the specimen,we must deconvolute: -Instrumental Broadening FW(I) also referred to as the Instrumental Profile,Instrumental FWHM Curve,Instrumental Peak Profile Specimen Broadening FW(S) also referred to as the Sample Profile,Specimen Profile We must then separate the different contributions to specimen broadening Crystallite size and microstrain broadening of diffraction peaksInstrument and Sample Contributions to the Peak Profile must be Deconvoluted
