Chemical warfare agents properties

Chemical warfare agents, such as soman and sarin, sometimes termed nerve gases, are powerful anticholinesterases, which bear some resemblance in structure and properties, to the OP insecticides. A major difference from most insecticides is their high volatility. These agents were possessed by the major powers during World War II, althongh they were never employed in warfare.

In spite of numerous researches devoted to improve methods and means for special treatment efficiency of decontamination in a number of instances does not correspond to the new requirements. An explanation for this from one side is the higher level of toxicity of the new chemical warfare agents small quantities of which could be very dangerous to humans and, from the other side, the process of decontamination is dependent both on methods and decontamination ability and specific properties of the contaminated object.

The properties of an ideal mass analyzer are well described, [2] but despite the tremendous improvements made, still no mass analyzer is perfect. To reach a deeper insight into the evolution of mass spectrometers the articles by Beynon, [3] Habfast and Aulinger, [4,5] Brunnee [6,7], Chapman et al. [8] and McLuckey [9] are recommended for further reading. In recent years, miniature mass analyzers have gained interest for in situ analysis, [10] e.g., in environmental [11] or biochemical applications, [12] for process monitoring, for detection of chemical warfare agents, for extraterrestrial applications, [13] and to improve Space Shuttle safety prior to launch.

Due to their unique properties, a large number of groups all over the world are working in the area of CNTs for diverse applications and the most important are development and fabrication of sensors and thermal protection for atmospheric re-entry of space vehicles. Gas and glucose sensors based on CNTs have been developed. Some American researchers have recently claimed that they have developed CNT-based sensors for the detection of chemical warfare agents [80].

Properties White crystalline solid. Sp. gr. 2.02. M. P. 52°, B. P. 61.5°. Vapor density 3.6. It polymerizes on storage into a physiologically inert substance and decomposes on contact with metals. A systemic poison, but rather unsuitable for use as a chemical warfare agent on account of its instability.
