Abstract

Techniques combining thermogravimetry (TG) and mass spectrometry (MS) are described whereby TG provides precise heating conditions and weight loss information and MS identifies volatiles evolved during the weight loss process. In the present work the DuPont 990 thermal analysis system, a DuPont 21–104 mass spectrometer, and a Hewlett-Packard 21-MX/Digital Equipment PDP-10 computer system are combined through simple, unique interfaces. The instrumentation features flexibility in thermal treatment of the sample and good atmospheric control. Testis with model substances and practical industrial problems have shown good enrichment and recovery of eluted components and no significant delay in TG operations.
