The objective of this presentation is to discuss the results of the evaluation studies conducted on four commercially available field-portable Raman spectrometers. The data presented in this comparison will affect the forensic science community by assisting a prospective user in determining which portable Raman device may best suit their agency’s needs. This presentation describes:
- The specifications of the four portable Raman instruments as evaluated in this study.
- A summary of the results and discussion of the technical evaluations.
- The strengths and opportunities for improvement of each device as perceived by the evaluators.
- A discussion of the limitations of portable Raman technology regarding the analyses of controlled substances and explosives performed in these evaluations.
