Analytical Tools - DSC/TGA and Elemental Analyzer
Abstract
In this proposal the absolute necessity for replacement of our aging andundependable TA Q10 differential scanning calorimeter/TA Q50 thermal gravimetricanalyzer (~13 years old) and Exeter CE 440 elemental analyzer (~10 years old) withmore modern and more dependable instrumentation is described. These two instrumentsplay such extremely valuable roles in the successful design and synthesis of newenergetic materials for the Office of Naval Research. The goal of our work for ONR is toenhance the capabilities of the U. S. Navy in meeting the challenges presented by theever increasing sophistication of the weapon systems of other nations. In order to movetoward this goal, our objective is to design, synthesize and characterize new high energycomponents with appropriate properties while concomitantly educating and trainingmembers of the work force of tomorrow. Two of our very recent coworkers (Ph.D. andpostdoctoral fellow) are currently employed at NSWC Indian Head and at NASCPatuxent River. The development and characterization of new energetic materials is anexciting and challenging area of chemistry. Considering the many applications ofenergetic materials as explosives or oxidizers, it is vital to discover new compositionswith significant advantages over current compounds. While new generation energeticmaterials must meet a variety of standards, two of the most important characteristics arepurity and thermal stability. Small amounts of impurities can markedly modify many ofthe properties. However, after careful purification, when the determined percentages ofthe major elements, i.e., carbon, nitrogen and hydrogen, support the proposedcomposition, it is possible to be confident that the other determined properties includingthe very important decomposition temperature (specs require ~150 ~C) should beaccurate. Thus, for a serious synthesis lab to operate properly both trustworthyDSC/TGA and elemental analyzer are required.
