    摘要： The invention relates to the use of at least one polymer comprising a repeating unit of formula (I): in which: X and Y=single bond or linear C1-C50 hydrocarbon group; R1 and R2=H, CN, C(Z)3, CH(Z)2, CH2Z with Z=halogen; NH2, NHR3, NR3R4 with R3, R4=halogen, CH3 or linear or branched, saturated or unsaturated C2-C20 hydrocarbon chain, optionally comprising one or more heteroatoms and/or chemical functions comprising at least one heteroatom; at least one from among R1 and R2 being ≠H; or of a composite comprising this polymer and one or more conductive charges, as sensitive material in a sensor for detecting nitro compounds. Applications: Detection of explosives, control/monitoring of atmospheric pollution and of ambient air quality, monitoring of industrial sites.

    摘要： It comprises a handle (1), an air flow amplifier (8) leading to a retention means (2) such as a cyclone via a passage (3), and a compressed air inlet device (7, 9) in the amplifier (8) that creates a strong suction of outside air, through the nozzle (4) capable of capturing even fine particles of low content up to a measurable quantity. Being completely devoid of electricity, this device is useful in hazardous atmospheres, in particular for detecting the presence of explosives after analysis of the particles collected by this device. It makes it possible to sample particles in extreme conditions of high or low temperatures.
