How can the TGA be used to compare two similar products?
Here two (2) types of coffees are compared, Zimbabwe in blue and Columbian in
red, using the same method conditions. The solid lines are the weight loss curves
and the dashed lines are their respective derivatives. The differences are easily
displayed, but it will take a coffee scientist to interpret the significance of the difference.
How can the TGA be used as a QA/QC tool to ensure products meet their material specifications?
here is a fiberglass reinforced printed circuit board. This analysis determines the amount of resin and the amount of fiberglass used in this material. The delta Y calculation was used to determine the component percentages. Resin = 44.144%; Glass = 56.854%. The resin decomposes in two steps, first rapidly, then slows as the last remaining resin decomposes.
Can the TGA be used to identify safe operating temperatures in various gases?
Here is an example of a weight gain experiment. A manganese sample was
run in a nitrogen atmosphere. The sample purge rate was 30 mL/minute. The delta Y calculation with calculation limits were arbitrarily set at 115 °C and 1190 °C. In this experiment the weight gain is due to the formation of manganese nitride. When manganese is run in argon, there is no weight change.
