Identification
Home Up Contents

 

Identification of unknown powder materials is a common, easily used technique available in the X-ray facility. 

Key Benefits

Non-destructive analysis
Minimal sample requirements (0.01 cc)
Easy sample prep
Fast results (usually less than 1 hour)

Capabilities

Fast Data Collection

For unknown crystalline material, a full scan covering the two-theta range of 5-90 degrees can be completed in 45 minutes.

Computer Aided Peak Finding

After the data has been collected, a list of peak positions and intensities can be produced in less than 5 minutes.

Database Search/Match

The peak list is compared against the full ICDD powder database for possible matches using computer-based algorigthms.  If the starting materials used to produce the sample are known, it only takes a few minutes to examine the list of possible hits to determine the unknown.
