Abstract
The design and operation of a bench-top high-pressure thermogravimetric analyser is described and illustrated. It has the following specifications: sample mass 1–100 mg; temperature range 25–700°; heating rate 0.1–10 deg/min; pressure range 0–50 bar of air, O2, N2, CO2, CO or H2. Mass and temperature are measured with a maximum error of 0.1 mg and 5 K for any conditions of pressure, temperature and heating rate. The instrument can be used to study substances under industrially realistic conditions of pressure and temperature and to perform high-pressure accelerated oxidation tests on lubricants and polymers. In these areas of application, the instrument offers a new standard of accuracy and ease of use which make it comparable to commercially available high-pressure DSC systems.
