 PDF-2 2018

Quantity + Value

How “good” is your database? The PDF-2 has just got even better! ICDD’s search-indexing software, SIeve, has been included FREE! We know that any database can get you an answer, but is it the right answer? You can trust your diffraction data to ICDD. All ICDD databases are reviewed, edited, and standardized prior to publication. You can now take advantage of our integrated data mining and search-indexing software and be confident with PDF-2 as a stand-alone database. Designed to get you the right answer, PDF-2 is the most cost effective license!

  • PDF-2 2018 features 298,258 entries for rapid and accurate phase identification.
  • The PDF-2 database is licensed for five (5) years and offers the highest value in the global marketplace. This value is due to its low annual cost amortized over the lifetime of the license, combined with its large content of powder and single crystal powder data, and its high level of quality with embedded software for data mining and search-indexing.
  • Quality and subfile filters combined with 68 different searches and 53 display fields enable you to target your results for more accurate identification. The database is not just a collection of numbers; it is a sophisticated data analysis tool.

Using PDF-2 2018

  • Subfile – select filters related to assigned subfiles/subclass.
  • Environment – select filters related to the environment (especially temperature and pressure).
  • Status – select filters based on the status of the pattern, which can be Primary, Active, or Deleted.
  • Quality Mark (QM) – select filters related to the quality evaluation assigned to the data.
  • Database – search the entire database or select the data entry source (i.e., ICDD (00) – ICDD’s experimental patterns).

A Powder Diffraction FileTM (PDF) Card displays all of the scientific and bibliographic data available for a particular PDF entry and is organized into the following categories:

  • 2D Structure
  • Equipment factors
  • Historic stick pattern and simulated pattern
  • Tabular view of reported data: PDF, Experimental, Physical, Crystal, Optical, Structure, Classifications, Cross-references, References, Comments

*Note: The availability of each feature varies by PDF entry.

ICDD’s search indexing program, SIeve for PDF-2, is now FREE. It is designed to search and identify unknown materials. SIeve is integrated into the ICDD database to allow the use of the extensive data mining interfaces, searches, and sorts available to improve accuracy and precision of the identification process. For example, users can utilize the extensive permutable searches in each database, then define their own search subfile or use any of the “application or expert-defined” subfiles and subclasses to increase the accuracy of their phase identification. In many cases, this provides a unique capability to analyze the most difficult problems.

SIeve offers a variety of algorithms and options that allow users to optimize results for particular chemistries and both standard and non-standard diffraction systems. SIeve features automatic rotation of the eight strongest lines (Hanawalt) or the eight longest of the strongest lines (Fink) or the eight longest lines (Long8) to look for entries that exhibit the best Goodness of Match (GOM). In the last few years, new algorithms have been added to identify non-crystalline materials and complex multi-phase specimens. Most of the algorithms were developed and optimized for a particular type of analysis and the options provide the user with a wide breadth of analytical capability. SIeve can be complementary with most commercial software programs. This complementary nature demonstrates the strength of SIeve in the analysis of minor and trace phases where the full filtering capability of the PDF-2 database can be applied.
