What is the primary purpose of the FirstDefender RMX in field operations?

• A. To identify unknown solid and liquid chemicals in the field
• B. To calibrate laboratory instruments
• C. To identify unknown gases in the field
• D. To analyze environmental samples

Answer: (A)

The main idea is that this handheld instrument is used for quick field identification of unknown chemical solids and liquids. It works by analyzing the sample with Raman spectroscopy and matching the resulting spectrum to a library, so responders can determine what the material is and decide on appropriate safety actions right there on scene.

Gases aren’t the primary focus because the RMX is built and used primarily for solids and liquids in the field, where a solid or liquid sample can be placed in the sampling window for analysis. Calibrating lab instruments or analyzing environmental samples are separate tasks that typically rely on different equipment and lab-based methods, not the core capability of this device.
