Quantitative analysis of polymer additives by coupled SFE/SFC.
Quantifizierung von Polymeradditiven mittels SFE/SFC-Kopplung
Supercritical carbon dioxide was used supercritical fluid extraction (SFE) coupled with supercritical fluid chromatography (SFC) to quantitatively analyze additives in polymers. A unique method was used to measure carbon dioxide flows at the system's outlets. Triacetine in Biopol and Irganox additives in Polypropylene were measured.
