Polymer additives are important for stabilization in manufacturing process and stabilization over time. This application note shows the analysis of selected a process, UV and oxidation stabilizers widely used in polymers. The samples are extracted under reflux and after polymer precipitation, the additives are analyzed by HPLC. The results are essential for quality control.
The antioxidants/UV stabilizers in the polyolefin granulate are analyzed by the standard addition method. These polymers are used as a catalytic media during crosslinking and further processing.
The aromatic hydrocarbons content of diesel fuel is a factor that can affect exhaust emissions and fuel combustion characteristics, as measured by cetane number. This application shows fast and robust method for the determination of monoaromatic, di-aromatic, and polyaromatic hydrocarbon contents in diesel fuels and petroleum distillates boiling in the range from 150 to 400 °C.
