Detection of Ultra-Small Residual Masses: Weigh The Little Bird!

Thermogravimetry (TGA) is frequently applied for the compositional analyses of such materials as, for example, fiber-reinforced polymer composites. The residual mass at the end of a TGA experiment reflects the filler or glass fiber content as well as the presence of impurities. By using a relatively large sample volume in a top-performing thermobalance along with the intelligent Proteus® software by NETZSCH, it is possible to detect ultra-small residual masses with concentrations down to the ppm (= 10-6) range! Such small concentrations can be illustrated by a little bird with a mass of a few grams sitting on the back of an elephant weighing a few tons.

Clear Raw Material Identification (RMID) Using DSC

Raw material identification or incoming goods inspection is of paramount importance for the quality and safety of drug products, wherever chemical substances are used in the pharmaceutical industry – maybe as an educt of chemical reactions or as a basis for further processing.

Studying Polymorphism by Means of DSC

From the chemical point of view, diamonds are just made of carbon. The phenomenon that chemical elements can occur in different forms within the same phase, i.e., in different structural modifications, is called allotropy. Due to the relationship between crystal modification and melting point, Differential Scanning Calorimetry (DSC) is ideally suited to discriminate between different polymorphic forms. A more general term for chemical compounds is polymorphism.
