Chemical Agent Detector Paper is a type of paper used for detecting the presence of chemical agents, including nerve agents, mustard agents, and blister agents. The paper typically change color in the presence of a chemical agent. The U.S. Military and first responders typically use the paper.

M8 Detector Paper
M8 Detector Paper is used to detect the presence of V and G type nerve agents and H type blister agents. It works by detecting chemical agents from a liquid splash. Each sheet of paper has three separate detection dyes. When there are G nerve agents, the yellow color appears, Dark Green color appears in the presence of V nerve agents, and the red color shows up when there are H blister agents. The M8 detector paper does not detect agents in the form of aerosols or vapors.

M9 Detector Tape
M9 Detector Tape or paper is used to detect the presence of nerve (V- and G- types) and mustard (H, HD, HN, and HT) agents. It cannot, however, identify what particular agent it is being exposed to. The tape is typically a dull cream color when not exposed to chemical agents, but will turn red in the presence of chemical agents. The tape is made from Mylar, which is the sticky backing, and a red agent detection dye. The detector tape does have false positives, which can be caused by antifreeze, petroleum-based products, and liquid insecticide.
