Thermogravimetric Analysis (TGA) has routinely been used to quantitatively determine the presence of a specific component within a material by direct measurement from the weight loss profile. This technique works well when it is known that the detected weight loss was caused only by that component. If more than one material evolves during a single weight loss it is impossible to quantify the contribution of each individual component by using stand-alone TGA. However by coupling an FT-IR to the TGA one may assign evolved gases to a detected weight loss and potentially isolate each iny dividual material. Although a number of gases may evolve during one weight loss, the judicious selection of "Specific Gas Profiles" may allow the experimentalist to isolate each gas. The SGP is a measure of IR absorbance within specific frequency regions as a function of time. Through the use of standards, integration of theseprofiles allows the operator to quantitate the various components in an unknownp. Data from this research will show that nitrocellulose andpulp content in gun powder samples may be measured using the TGA/FT-IR technique.
