Forensics

Essential investigations

The use of analytical instrumentation to uncover facts from even the smallest traces of evidence plays a key role in today's forensic laboratories. A wide range of techniques is employed, but analytical X-ray methods, X-ray diffraction (XRD) and X-ray fluorescence (XRF), are becoming increasingly important for routine analysis. The addition of high resolution Computed Tomography (CT) scanning with XRD or XRF provides the ultimate non-destructive comparative analysis solution.

Why X-ray analysis?

From the analysis of crime-scene evidence, explosives and bullet residue, soil samples, paint chips, duct tape, cosmetics, illicit drugs, drug precursors and counterfeit medicines to the notorious 'unknown white powder', XRD and XRF provide the data essential in modern criminal investigations. The techniques deliver:

• speed, accuracy and reproducibility of results
• flexibility – data can be provided on a diverse range of sample types
• simplicity of sample preparation
• non-destructive nature of measurement
  
  

PANalytical leadership

PANalytical's state-of-the-art XRD and XRF systems, complete with advanced software packages, are already widely used in many police departments, government forensics labs and university forensics departments around the world.

XRD landmarks:

• Empyrean has the unique possibility to combine conventional powder diffraction, microdiffraction for spatially resolved phase analysis and computed tomography for the microstructural investigation of samples on one system

XRF landmarks:

• Axios range – complete elemental analysis
• Epsilon 5 – trace elemental analysis
• All PANalytical XRF platforms have standardless analysis packages. Omnian sets the benchmark
• MiniPal range portable FingerPrint, rapid material identification
• Omnian – the most comprehensive standardless package
