Assignee:
University of Massachusetts - Boston MA
International Classification:
G01N 700
US Classification:
422 83, 422 78, 422 80, 422147, 422 94, 73 2336, 73 3515, 73 3516, 73 3517, 436155
Abstract:
The invention features methods and systems for detecting the presence of an energetic material in a sample in which the presence of the energetic material is unknown. The method includes the steps of: heating the sample; measuring heat flow between the sample and its surrounding environment, e. g. , by using differential scanning calorimetry (DSC); and analyzing the measured heat flow between the sample and its surrounding environment. An exothermal peak in the measured heat flow indicates the presence of the energetic material in the sample. The system includes a thermal measuring apparatus for performing the heating and measuring steps, and an analyzer for detecting the presence of the energetic material based on the measured heat flow. The invention also features methods and systems for identifying contraband materials (e. g. , explosives and drugs) by measuring the thermogram (e. g.
