Forensics

Element / phase analysis and molecular structure

X-ray analytical methods have a long history as important tools to investigate and establish facts in criminal or civil courts of law to analyze, identify or compare unknown materials. Small spot X-ray fluorescence (XRF) is a non-destructive method to determine concentration and distribution of chemical elements such as Pb and Cu residue from bullet holes in clothing, for example. X-ray diffraction (XRD) can identify chemical phases in complete unknowns. Both techniques allow standardless quantification of element concentrations and phase composition. Rigaku's Raman spectrometer Progeny ResQ 1064 nm provides the industry’s most comprehensive tool for fast and reliable chemical identification, CBRNe detection and narcotics classification in a simple and easy-to-use handheld form.

Rigaku recommends the following systems:


WDXRF

Benchtop tube below sequential WDXRF spectrometer analyzes O through U in solids, liquids and powders

High power, tube above, sequential WDXRF spectrometer with new ZSX Guidance expert system software

WDXRF spectrometer designed to handle very large and/or heavy samples

High-throughput tube-above multi-channel simultaneous WDXRF spectrometer analyzes Be through U

XRD

New 6th-generation general purpose benchtop XRD system for phase i.d and phase quantification
