The First Defender RMX is designed to identify

• A. Unknown solid & liquid chemicals in field
• B. Unknown gases in soil
• C. Radiation levels in air
• D. Water contaminants in streams

Answer: (A)

The main capability being tested is handheld chemical identification of unknown substances in field-solid or liquid form. The First Defender RMX is a portable Raman spectroscopy tool designed to analyze solids and liquids directly on scene, providing rapid identification of unknown chemicals by comparing the measured Raman spectrum to a library. It excels at pinpointing what a sample is when you have a solid or liquid material on-site, with minimal or no sample preparation.

It’s not built to identify unknown gases in soil, measure radiation levels in air, or test water contaminants in streams. Gas identification would require a different gas-detection approach, a radiation-detection device is needed for measuring radiation, and water contamination assessment typically involves water sampling and analysis, not surface Raman of solid/liquid samples.
