Identify and Quantitate

The PDF-4+ database is ICDD's most advanced database, designed for both phase identification and quantitative analysis. For quantitative analysis, the database has the following features:

PDF-4+ 2015 contains 365,877 entries. It combines the world’s largest sources of inorganic diffraction data from crystals and powders into a single database. The result is a comprehensive collection of inorganic materials, produced in a standardized format that can be rapidly searched for unknown phase identification. Extensive data mining is facilitated with our 116 display fields coupled with >60 searches.

PDF-4+ is designed to support automated quantitative analyses by providing key reference data required for these analyses. It also contains an array of tools that supplement conventional analyses, such as a full suite of data simulation programs enabling the analysis of neutron, electron, and synchrotron data, in addition to conventional X-ray data. PDF-4+ features digitized patterns, molecular graphics, and atomic coordinates. These features have been incorporated into PDF-4+ to enhance the ability to do quantitative analysis using third party software by any of three methods: Rietveld Analysis, Reference Intensity Ratio (RIR) Method or Total Pattern Analysis.
