Title:
SYSTEM AND METHOD OF DETECTING EXPLOSIVE COMPOUNDS BASED ON RAPID DEFLAGRATION AND DIFFERENTIAL MICRO-CALORIMETRY
Document Type and Number:
WIPO Patent Application WO/2017/051430
Kind Code:
A3
Abstract:
An explosive detection system for detecting explosive trace in a sample includes a detection unit, and a processing unit. The detection unit that receives a desorbed sample includes a first heater, a second heater, a first resistance temperature detector (RTD), a second RTD, and an amplifier. The first heater is exposed to the desorbed sample. The first heater and the second heater are supplied with specific voltage for three or more experiments. The first RTD and the second RTD measure changes in resistance due to heating of the first heater and the second heater to calculate voltages across the first RTD and the second RTD. The amplifier amplifies the voltages to calculate a differential voltage for each of the three or more experiments, and converts the differential voltage into a digital signal. The processing unit is configured to process the digital signal to detect explosive trace in the desorbed sample.
