ganic solutions and the UV-vis is able to identify both the molecules present and the concentration of those molecules. Differential Scanning Calorimeter (DSC): The DSC heats very small samples according to a planned program (degrees/minute) and charts the sample's response to the applied heat. DSC is used for energetic materials, propellants, plastics and other polymers, organic materials, inorgan

Applications for this technique include the identification of energetic materials from the residues they leave behind, separation and identification of metal ions from solutions of mixed ions, and identification of ion conc
