Electrical, electrochemical, and thermometric sensors for the detection of explosives

Аннотация

The main analytical characteristics of electrical, electrochemical, and thermometric sensors in the detection of vapors and traces of explosives and accompanying substances are compared. The limits of detection, sensitivity, sensor setting time (response speed) and, recovery time after exposure to analytes, and the selectivity of sensors are discussed. The efficiency of using nanodimensional structures in the sensing elements of sensors is investigated.
