Application: Forensic Science

JEOL Scanning Electron Microscopes and Mass Spectrometers are used by forensic investigators in crime labs, forensic science centers, and government agencies. The imaging and analytical ability of these sensitive yet easy-to-use instruments reveal physical and chemical details about evidence and provide answers to questions of identification.

Scanning Electron Microscopy

Focus on the evidence. Preserve the evidence. Investigate and compare. JEOL scanning electron microscopes enable imaging and analysis of the smallest details in forensic microscopy. Investigators can calculate 3D measurements from stereo images, contrast and compare fine details, and determine elemental composition. With its large specimen chamber and automated eucentric stage, the InTouchScope series SEM can accommodate large pieces of evidence in their native state for both imaging and chemical analysis.

JEOL high throughput SEMs focus on the smallest details and enable both high resolution imaging and chemical analysis for crime scene investigation and accident reconstruction. The SEM provides forensic details regarding:

fibers
glass
metal parts
electronic components
ballistics

explosive residues
toxicology
arson investigation
gunshot residue
trace evidence

failure analysis
drug analysis
paint chips
plant materials

JEOL Scanning Electron Microscopes are versatile, easy-to-use, high throughput instruments for the forensic scientist. Learn more about the JSM-IT700HR.

Mass Spectrometry

Unique chemical compositions provide clues to the identity of trace evidence, powders, and fragments of materials when analyzed by mass spectrometry. JEOL offers a unique solution for real time analysis that frees the investigator from typical sample preparation and provides instant results.

JEOL's unique Mass Spectrometry system identifies a wide range of materials, vapors, and liquids by their chemical composition, and enables direct analysis in real time of unadulterated samples including:

white powders
trace evidence
explosives
illicit drugs
plant materials

inks and dyes
fingerprints
bodily fluids
contraband
tapes and adhesives

fibers
smokeless powders
rubber
questioned documents
flavors and fragrances

The AccuTOF™-DART® has revolutionized mass spectrometry by providing comprehensive chemical analysis in real time, without the sample preparation required for traditional techniques. The AccuTOF-DART has gained widespread use at leading forensics labs.
