Evidence Collection

Arson
From biological and toxicological evidence to DNA samples, materials found at a crime scene can vary exponentially. Thermo offers a range of devices and portable analytical instruments to ensure efficient and secure evidence collection transport as well as thorough analysis of the crime scene for trace possibilities. Thermo also provides a full line of disaster pouches, plastic cadaver bags, and heavy duty vinyl bags to ensure organic materials including cadavers can be transported and protected from exposure.

Raman Spectroscopy

Raman is a rising star for forensic sciences. Its major advantage is in its ease of sample handling. No dilutions are required, nor does the suspect material need to be extracted from the background. You can test Raman samples through glass and plastics for contamination-free data collection. Raman complements FT-IR and can identify materials that are difficult to analyze with FT-IR. Raman microscopy also offers spatial resolution to 1 micron.

Typical Materials for Raman Analysis

  • Bulk or micro materials
  • Fibers
  • Dyes
  • Inks
  • Paint chips
  • Illicit drugs
  • Crystalline structures (polymorphs)
  • Inorganics & organics
  • Liquids and solids (gas accessories available)

Infrared Spectroscopy

In forensics science, Infrared spectroscopy is regarded as a relatively inexpensive technique capable of quickly and simply indentifying materials without the need for direct contact with the evidence. Fourier Transform Infrared (FT-IR) spectrometers from Thermo Fisher Scientific couple numerous sampling techniques with extensive spectral libraries, and enable you to identify just about any sample that comes through the lab.

Gas Chromatography

In today’s drug testing, toxicology, and forensic labs, accelerated turn-around time and minimum cost per sample are vital for achieving critical productivity goals. For almost 40 years, Thermo Scientific has been developing solutions to provide busy laboratories with increased productivity. By giving you the tools to analyze higher numbers of samples than ever before, Thermo Fisher Scientific tries to maintain the quality of your chemical and trace analyses..
