Download this application note to learn how to rapidly and accurately determine arsenic in apple juice using HPLC/ICP-MS.

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.
