PANalytical

Advanced forensic technologies enabling accurate analysis of unique samples

X-ray diffraction (XRD) and X-ray fluorescence (XRF) are becoming increasingly important techniques for non-destructive routine analysis. Both techniques provide clear phase and elemental data to the forensic scientist, which is vital in criminal investigations.

PANalytical's state-of-the-art XRD and XRF systems, complete with advanced software packages and specialized databases, are used worldwide in many police departments, government forensics labs and university forensics departments. The XRD platform combines conventional powder diffraction, computed tomography (CT), micro-diffraction and small-angle X-ray scattering (SAXS).

PANalytical’s XRF technologies offer non-destructive analysis with very high sensitivity and simple or no sample preparation. Elemental analysis using Omnian standardless analysis packages can be performed on just milligrams of sample. Instrument Qualification (IQ) and Operational Qualification (OQ) procedures, originally designed for the pharmaceutical industry, validate instrument performance. Finally, Audit Trail and Enhanced Data Security functionality record the sample analysis and data processing history.

Examples of forensic applications and X-ray technologies used by the community are listed below.

X-ray Diffraction

Empyrean
Typical forensic uses include:
• Bullet identification and mineral residue by micro-diffraction
• Identification of crime scene soils, paints and associated residuals
• counterfeit material identification
• controlled substances identification using the CanDI-X database
• Cluster analyses – identifying subtle differences and trafficking routes
• Non-intrusive CT visualization for internal macro structural examinations

X’Pert³ Powder
Typical forensic uses include:
• Bullet identification and mineral residue by micro-diffraction
• Identification of crime scene soils, paints and associated residuals
• counterfeit material identification
• controlled substances identification using the CanDI-X database
• Cluster analyses – identifying subtle differences and trafficking routes

X-ray Fluorescence

Epsilon 3X spectrometers (energy dispersive XRF)
Typical forensic uses include:
• On-site soil analysis
FingerPrint identification of counterfeit materials (foods, personal care items, fuels)
• Large and irregular shaped material chemical analysis
• Standardless material analysis when combined with Omnian

Zetium (wavelength and energy dispersive XRF)
Typical forensic uses include:
• Trace element soil and mineral elemental analysis when combined with Pro-Trace
• Standardless material analysis when combined with Omnian
