FirstDefender RM Mobile Raman Spectrometer

Identifies unknown chemicals within seconds

Mobile Raman spectrometer FirstDefender RM

The FirstDefender RM is a handheld Raman spectrometer. In just a few seconds, it identifies liquid and solid hazardous substances as well as mixtures of substances. The identification of chemicals is contactless and non-destructive, even through transparent glass or plastic containers. This enables emergency services to react quickly and correctly. The integrated DecisionEngine software provides clear and unambiguous results that do not need to be interpreted by the user. This reduces the need for on-site scientific personnel.

Large chemical database

The integrated chemical database contains over 11,000 substances, including explosives, TICs/TIMs, chemical warfare agents, narcotics, "white powders", precursor substances, etc. Additional hazardous material and safety information is provided for each substance.

Automatic mixture analysis greatly expands identification capabilities without the need to subtract spectra. The intuitive, menu-driven user interface enables best results after minimal training. The instrument is suitable for operation while wearing a protective suit. It operates continuously for 4 h with a replaceable lithium-ion battery.
