General Description
Colorimetric Enzyme-Based Spray that detects chemical agents directly on surfaces via a visible color change within 5 minutes. The formulation detects Sulfur Mustard Blister Agent (HD) with microgram sensitivity. The Blister Agent Disclosure Spray is sold in three form factors: a half-liter handheld sprayer capable of covering 5-7 square meters of surface; a man-portable sprayer, the Viper Discovery applicator, which contains approximately 2 gallons of the formulation and covers 75 – 120 square meters of surface area; and the Merlin Discovery cart-based sprayer, which holds 14 gallons and is capable of covering 500-700 square meters.
