Analysis of Additives in a Polymer
Using the Agilent 6120B Single Quadrupole MS and MassWorks accurate mass elemental composition determination software.
High molecular weight materials, such as plastics, are indispensable in daily life. High molecular weight materials contain traces of additives such as antioxidants and ultraviolet-absorbing compounds. It is important to understand their impact on the polymer and its quality. High-performance liquid chromatography (HPLC) is an analytical method that is effective for the qualitative and quantitative analysis of these additives. In HPLC, UV detection is the most common detector used, but it is difficult to identify unknown components by UV, due to a lack of specificity. A more powerful, affordable, and simple-to-operate alternative is a single quadrupole LC/MS.
