General Description
M9 chemical detection papers were originally developed for the military to detect liquid nerve and blister agents. M9 Chemical Detection is used by ground forces and is placed on personnel and equipment to identify the presence of liquid chemical agent aerosols. It contains a suspension of an agent sensitive red indicator dye in a paper matrix. It will detect and turn pink, red, reddish brown or redpurple when exposed to liquid nerve agents and blister agents, but it does not identify the specific agent, nor does it detect any biological agents, such as anthrax.
Technical Description
M9 Paper is actually a coated tape with a mylar-adhesive backing so it can be affixed to objects. It's packaged in a dispenser with a serrated edge to easily tear off sections for use. M9 contains a suspension of an agent-sensitive red indicator dye on the paper. The dye will turn pink, red, reddish-brown, or red-purple when exposed to a liquid agent. Agents do not react directly with the dyes in M8 paper, but rather, dyes react to the unique acidity of each of the agents to produce the color change in a manner similar to litmus paper. M9 Paper can detect agents, but not identify which agents are present. The tape that makes up M9 is 9.1 meters long and 5.1 centimeters wide. The selfadhesive paper attaches to most surfaces, and a moisture proof resealable bag is provided to store the dispenser after removal from its original packaging.
