Extract

In the past, we were limited to manual methods for the identification process. Identification was done manually with a data base of reference spectra (in card and search manual format) supplied by the Joint Committee on Powder Diffraction Standards (JCPDS). Most single substances can be identified with relative ease using this approach. But when the number of components gets much beyond two, the measured pattern is a complex composite of sub-patterns which makes the identification a tedious and uncertain process taking 60 to 90 minutes per pattern in most simple cases.
