Balance and furnace
THEMYS HP is a robust, flexible high pressure thermogravimetric analyzer featuring:
- HIGH PRESSURE model, a specific pressure-rated balance. It is designed based on the vertical hang-down principle for the best mass signal accuracy and stability.
- An alumina protected furnace with a platinum based heating element for isothermal or temperature scanning operations at heating rates up to 100 °C/min. The same furnace and balance cover a temperature and pressure range up to 1 200 °C and 150 bar with the best TGA detection limit. It avoids multiple furnace changes for different samples or test conditions.
The high-performance gas panel specially designed for THEMYS HP TGA is equipped with a dual back pressure regulating device able to accurately control the test pressure during both low and high pressure operations.
Two optional versions equipped with high pressure Mass Flow Controllers (MFC) are available for complex atmosphere control and gas mixtures:
- Single gas flow control with a 4 to 200 ml/min MFC meant to flow a pure or premixed gas in the THEMYS HP TGA,
- Advanced control gas panel equipped with two high pressure MFC (Mass Flow Controllers), 3 carrier gas inlets and 1 auxiliary gas inlet.
THEMYS HP is typically applied to the study of pyrolysis, combustion, gasification conditions met in many coal, biomass or waste to energy processes. It is also designed for high temperature and pressure corrosion studies, and more particularly with alloys used in the above mentioned processes.
THEMYS HP is the ideal tool for sorption and desorption analysis in the fields of gas capture and storage, gas sensing materials characterization, or more generally sorbent materials characterization.
