Independent Validation of microRAMAN RS-uRM10 by Fraunhofer ICT
Fraunhofer ICT Confirms Performance of the microRAMAN RS-uRM10 Handheld Spectrometer
The microRAMAN RS-uRM10 handheld Raman spectrometer developed by RS DYNAMICS underwent an independent laboratory evaluation at the Fraunhofer Institute for Chemical Technology (Fraunhofer ICT, Germany) between May and July 2025.
The testing program focused on analytical performance, identification capability, detection sensitivity and time-to-result measurements.
The instrument was evaluated across a broad range of representative samples including explosives, pharmaceuticals and psychoactive substances, food additives, organic chemicals, inorganic chemicals and liquid samples.

High Identification Success Rate
The testing demonstrated successful identification across the vast majority of evaluated substances. Results included correct identification using the factory spectral library, correct identification using user-added libraries and successful component recognition in complex samples.
The tested configuration used the ST Japan spectral database containing more than 24,000 spectra.
Detection Limits Down to 0.5% V/V
Fraunhofer ICT evaluated the sensitivity of the instrument using diluted chemical solutions. Selected compounds remained identifiable at concentrations around 0.5% V/V, while some substances were successfully detected at even lower concentrations.
The achievable detection limit is about 0.5% V/V for selected substances.
Trace Detection Capability
The evaluation included testing with trace quantities of energetic materials prepared using precision nanoplotter technology. Fraunhofer ICT reported that the practical detection capability is below microgram level.
This capability is particularly relevant for security screening, forensic investigations, hazardous material response and explosives detection applications.
Identification in as Little as 1.5 Seconds
Speed testing was performed on multiple representative substances including sulfur, toluene, acetone and isopropanol.
The achievable identification time is about 1.5 seconds for selected substances in limited library set.
Fast identification supports rapid decision-making in field operations where immediate analytical feedback is critical.

Why Independent Validation Matters
Independent third-party testing provides objective verification of instrument performance and helps users evaluate analytical capabilities based on documented evidence.
The Fraunhofer ICT evaluation demonstrates that the microRAMAN RS-uRM10 delivers rapid substance identification, trace detection capability, low-concentration sensitivity, broad chemical coverage and field-ready analytical performance.
These capabilities support applications in security, defense, customs, emergency response, industrial safety and laboratory analysis.
