Forensics Applications of Klarite®

Klarite offers unique advantages in the analysis and identification of substances from an incident scene.

The use of Klarite substrates for Raman spectroscopy enables unique chemical fingerprints to be obtained at lower concentrations and smaller sample sizes than previously possible.

By placing an unknown sample onto the Klarite surface and then performing a Raman analysis, trace concentrations can be seen and identified. The chemical fingerprint can then be compared to known substances to establish its source or look for impurities in the sample.

Liquid samples can be deposited directly onto the substrate. Solid or dried samples can be dissolved and placed on the Klarite surface for analysis. No sample pre-treatment is necessary. Klarite substrates are individually numbered and bar-coded and can be stored and analysed many times.

Partners are actively being sought by Renishaw Diagnostics to exploit the forensics  applications potential of Klarite.

Benefits of Klarite in Forensic Science

The million-fold increase in sensitivity observed using Klarite substrates in conjunction with Raman systems enables small quantities to be detected, and chemical fingerprint data to be compared and analysed.

• Extremely low levels of detection and identification
• Small sample volumes
• Sample can be analysed many times – non destructive
• Ease of use
• Single-use, re-testable substrates – better for archiving
