Analysis of calcium oxalate and polystyrene in oxidizing atmosphere using high-resolution TG-TOFMS
MSTips No. 350
Thermogravimetric-mass spectrometry (TG-MS) is a measurement technique for obtaining weight change and qualitative information of evolved gas during heating. It is used to evaluate resins and synthetic rubber products. Usually, the inert gas such as helium and nitrogen are used as the TG atmosphere gas. On the other hand, oxidizing atmosphere measurement such as the air will be effective for product development and quality control. However, the electron ionization (EI) method, which is a standard ionization method, is difficult to analyze for a long time under oxygen due to deterioration of the filament. We have developed an oxygen-resistant filament to solve this issue. We have introduced the oxygen-resistant filament application note for QMS in MSTips No. 320. In this MSTips, we introduce anti-oxygen filament application data for high-resolution TOFMS.
