Extract

The availability of automated powder diffractometers, APD, has revolutionized the collection of diffraction data and allowed many improvements in the analysis of these data. The biggest change is the ease of digitizing the diffraction trace rather than preparing it as a strip chart on paper from an analog recorder. When the data are collected properly, the trace is a digitized record of intensity versus 2θ. The trace is an accurate representation of the diffraction pattern containing the sample information along with the spectral and instrument aberrations.
