Abstract : Sarin, a well-known chemical warfare agent, is toxic for concentrations as low as 0.03 ppm in the air (Immediately Dangerous to Life or Health value). A technology providing "on the field" detection could be fluorescence spectroscopy. This presentation shows a sensitive method for the detection of Diethyl Chlorophosphate (DCP), a Sarin surrogate, which provides in a few seconds a turn-off fluorescence response of the sensor for ppb levels of DCP. For instance, a I/I0 = 0.68 (fluorescence quenching) was obtained when the sensor was exposed to 16 ppb of DCP.
