XRD and XRF Analysis

Advanced Nondestructive analytical techniques are increasingly making use of X-ray diffraction (XRD) and X-ray fluorescence (XRF) for non-intrusive and often fast routine analysis.

In technical terms, both techniques will provide clear phase and elemental data to the forensics that can come in vital in situations such as criminal investigations or failure/accidents.

At 3Dforms, we employ state-of-the-art XRD and XRF systems that are increasingly widely used in many police departments, government forensics labs and university forensics departments. With XRD we quickly use conventional powder diffraction, computed tomography (CT), micro-diffraction and small-angle X-ray scattering (SAXS) the most advanced analytical techniques to get as accurately data as can possibly be got.
With the XRF technique on the other hand, we offer non-destructive analysis with very high sensitivity and simple or no sample preparation necessary whatsoever. Elemental analysis using can in some cases be performed on just milligrams of sample.

Below is some of the examples of common uses of forensic applications and X-ray technologies in use today.

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

Epsilon 5 (energy dispersive XRF)
Typical forensic uses include:
• Elemental analysis of delicate sample types including biological tissues
• Standardless material analysis when combined with AutoQuantify
• Food (rice, mushroom, spinach) and tobacco origin and counterfeit identification

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
