Which database is right for you?
The Powder Diffraction File is designed and produced in several different
formats in order to serve different groups of users. All PDF databases
include integrated data mining software.
PDF-2 – Phase Identification
PDF-2 is a collaborative product between ICDD, FIZ and NIST and is
designed for inorganic materials analyses. Many common organic
materials from ICDD are added to this database to facilitate rapid
PDF-4+ – Phase Identification
and Quantitative Analysis
PDF-4+ is our most advanced database, designed for both phase
identification and quantitative analysis. It contains the data from both
the PDF-2 and ICDD's collaboration with MPDS. This database has
comprehensive material coverage for inorganic materials and it contains
numerous additional features such as digitized patterns, molecular
graphics and atomic parameters. Features to enhance the ability
to do quantitative analysis have been incorporated into PDF-4+.
WebPDF-4+ – PDF-4+ "On the Go"
WebPDF-4+ provides the needed portability for accessing the PDF-
4+ database via the internet. It enables full functionality of the PDF-
4+ database using a high-speed internet connection. WebPDF-4+ is
delivered as a USB compatible dongle.
PDF-4/Minerals – The most comprehensive
collection of mineral data!
PDF-4/Minerals represents ninety-seven percent of all known mineral
types, as defined by the International Mineralogical Association (IMA),
as well as many unclassified minerals. PDF-4/Minerals is a subset of
the PDF-4+ database, which includes all of the software features
incorporated into PDF-4+.
PDF-4/Organics - The largest X-ray powder
diffraction database for organics!
PDF-4/Organics is the world's largest X-ray powder diffraction database
for organics. It is designed for a multitude of applications in
pharmaceutical, regulatory, specialty chemical, biomaterials and
forensic fields. The product has all of the display software and data
mining capabilities contained in the PDF-4 family of products.
