Abstract
Rose Bengal for detecting a presence of chemical warfare agents. A method of detecting presence of a chemical warfare agent and includes applying a quinoid form of Rose Bengal to a substrate. When the substrate is exposed to the chemical warfare agent, a lactone form of Rose Bengal is spectrally observed because presence of the chemical warfare agent converts the quinoid form to the lactone form of Rose Bengal.
Claims22
A method of detecting presence of a chemical warfare agent, the method comprising:
- applying a quinoid form of Rose Bengal to a substrate;
- exposing the substrate to a chemical warfare agent;
- and
- spectrally observing a lactone form of Rose Bengal,
- wherein the chemical warfare agent converts the quinoid form to the lactone form of Rose Bengal.
A method of determining presence of a chemical warfare agent, the method comprising:
- applying a quinoid form of Rose Bengal to a substrate;
- spectrally observing the applied Rose Bengal, and
- concluding chemical warfare agent contamination if the observed spectrum corresponds to a lactone form of Rose Bengal or concluding no chemical warfare agent contamination if the observed spectrum corresponds to the quinoid form of Rose Bengal.
A method of detecting presence of a chemical warfare agent, the method comprising:
- applying a quinoid form of Rose Bengal to a substrate;
- exposing the substrate to a nerve chemical warfare agent or a blister chemical warfare agent;
- spectrally observing a lactone form of Rose Bengal;
- and
- observing a fluorescent signature of the exposed substrate.
