Since the function of a protein is closely related to its structure, the structural analysis of proteins and peptides is becoming increasingly important to assist in deciphering bioactivity. CD measurements are easy to obtain, and small sample volumes can be used. Additionally, conformational changes of proteins and peptides due to pH, temperature and external ligands can also be obtained.

Modern paints and varnishes are complex mixtures and the optimization of the material properties is an important task. One of the most essential variables is the curing which should in most cases take place in a reasonably short time span that can range from a fraction of a second to many days. It is difficult to evaluate the degree of the curing and its completeness by visual inspection. Therefore, an unbiased and reliable quantitative analysis is needed in quality control but also in R&D to optimize the varnish or the curing method respectively.

Thermal decomposition provides valuable information about the chemical composition of a material. Although thermal gravimetric analysis (TGA) measures small weight losses during a heating ramp, it cannot identify the chemicals corresponding to the weight loss.
