Compared to M9, what is true about M8?

• A. It identifies the specific type of chemical agent
• B. It is cheaper
• C. It detects more agents
• D. It works without reagents

Answer: (A)

In field chemical detection, some kits not only show that a chemical agent is present but also help you identify what type it is. M8 uses colorimetric indicators that respond differently depending on the agent, so you can tell whether you’re dealing with a nerve agent or a blister agent. M9, by contrast, mainly signals that a liquid chemical agent is present on a surface without identifying the specific agent. Because M8 provides this type-specific information from the test results, it’s the best description of how it compares to M9. This distinction matters in choosing protective actions and decontamination steps in the moment.
