Method
Thermogravimetry using Magnetic Suspension Balance Technology
Thermogravimetric Analysis (TGA) measures the change in sample mass as a function of temperature or time under a controlled atmosphere.
In the LINSEIS TGA L87 MSB, this method is implemented through a magnetic suspension balance, which enables contact-free weighing of the sample across a wide range of temperatures, pressures, and gas compositions.
The sample is magnetically coupled to an external microbalance, allowing the measuring chamber to be hermetically sealed from the sensitive balance system.
This unique setup permits highly accurate measurements under inert, oxidizing, reducing, reactive or vacuum conditions, as well as at pressures up to 350 bar and temperatures up to 2400 °C.
The method provides precise insights into decomposition, oxidation, reduction, adsorption, and desorption processes under real process conditions.
By quantifying these mass changes, TGA with magnetic suspension technology enables the determination of material composition, evaluation of thermal stability, and characterization of gas–solid interactions.
This makes it an indispensable tool for advanced material research, catalysis studies, gas storage analysis and high-pressure thermochemical investigations.
Functional Principle of the TGA L87 MSB
The TGA L87 MSB determines changes in sample mass as a function of temperature or time under precisely controlled atmospheric and pressure conditions.
Unlike conventional thermogravimetric analyzers, the MSB employs a magnetic suspension balance, enabling contact-free weighing of the sample inside a sealed reaction chamber.
During measurement, the sample holder is magnetically coupled to an external microbalance, allowing the balance to remain completely isolated from high temperature, high pressure, or chemically reactive environments.
This design ensures exceptional stability and protection of the weighing system while maintaining microgram-level precision even under extreme experimental conditions.
Mass changes caused by decomposition, oxidation, reduction, adsorption or desorption are continuously recorded throughout the entire temperature or pressure cycle.
The resulting data provide detailed insight into reaction kinetics, material stability, gas–solid interactions and process behavior under real operating conditions.
With its advanced furnace design, gas and vapor control systems, and wide operating range up to 2400 °C and 350 bar, the LINSEIS TGA L87 MSB delivers reliable, reproducible, and high-resolution results for demanding research and industrial applications.

TGA L87 MSB explained – function, use and capabilities
Measuring Principle
Default Position
In the standby position, both the lower cage and the upper cone rest on the support of the measuring system. No weighing is performed in this state, ensuring system stability and readiness for operation.
Calibration Position
During calibration, the cone is magnetically coupled and held
within the cage, causing only the upper suspension rod to levitate.
This allows precise determination and calibration of the balance signal under defi ned conditions.
Measurement position
In the measurement mode, the magnetic coupling lifts both the cage and the sample holder. The complete sample weight is transmitted to the balance, enabling accurate and reproducible measurement of the sample mass under real experimental conditions.
Forced Flow
Forced-flow offers several advantages in the investigation of gas/solid phase reactions
Patent pending
- Controlled Conditions: Precise control of reaction conditions for a reproducible environment.
- Faster Reaction Times: Acceleration of slow reactions through continuous flow.
- Better Mixing: Uniform distribution of reactants for improved reaction kinetics.
- Scalability: Easier adaptation to different volumes and flow rates for optimized production.
The illustration on the left shows a schematic representation of the weight measurement of a TGA L87 MSB.
The image on the right shows the principle of forced flow operation in a magnetic suspension balance. The sample gas is passed completely through the solid material and exits at the top. This significantly optimises the reproducibility, reaction control and significance of the measurement results.
What is the TGA L87 MSB used for?

Application example: Isothermal adsorption by Zeolite
The adsorption behavior of a zeolite sample was investigated under isothermal conditions using the MSB L87.
The experiment was performed at room temperature with a stepwise pressure increase from 0.1 to 2.0 bar. At each pressure step, the uptake of gas molecules by the zeolite framework was monitored through the corresponding sample mass increase. The recorded adsorption capacities ranged from 0.461 mg at 0.1 bar up to 10.576 mg at 2.0 bar. The stepwise isotherm clearly demonstrates the high affinity and capacity of zeolite
materials for gas adsorption.
Application example: Catalyst coking
The example illustrates the formation of coke on a catalytic material under process-relevant conditions of 20 bar and 650 °C in a reactive CH₄/H₂O atmosphere. As the steam partial pressure is gradually reduced, the reaction equilibrium shifts toward carbon formation, leading to a continuous mass increase of the catalyst due to coke deposition. The maximum specific coke deposition rate determined from the measurement is 0.32 mg g-1 s-1, highlighting the strong influence of steam concentration on the coking behavior of the catalyst.
Energy Industry
Thermogravimetric analysis (TGA) is a key technique in the development of modern energy technologies.
The LINSEIS TGA L87 MSB enables highly precise investigations of materials used in energy storage, fuel conversion, and gas purification, even under extreme temperature and pressure conditions.
By continuously measuring mass changes during heating, cooling, or pressure variations, the system provides detailed insights into reaction kinetics, sorption behavior, and thermal stability of fuels, catalysts, and storage materials.
This makes it ideal for studying processes such as biogas upgrading, CO₂ capture, hydrogen storage, pyrolysis, and coal or biomass gasification.
With its magnetic suspension balance technology, the TGA L87 MSB allows contact-free weighing in reactive or corrosive atmospheres up to 2400 °C and 350 bar, ensuring the highest precision and reproducibility.
These capabilities support research and development efforts aimed at improving energy efficiency, sustainability, and process reliability across the energy industry.
Application example: Adsorption of Biogas on Zeolite
The adsorption behavior of biogas components was investigated using the LINSEIS MSB L87.
Pure gas isotherms of CO₂, CH₄, N₂ and H₂ were measured on zeolite, an industrially relevant sorbent for biogas purification. With increasing importance of biogas as an energy source, the purification of its gas components is gaining significance. In combination with an appropriate dosing system, the instrument also enables the determination of gas mixture adsorption. This experiment demonstrates the capability of the MSB for precise sorption measurements under controlled conditions.
Application example: Coal gasifi cation
The gasification behavior of coal was studied at 50 bar using the
LINSEIS MSB L87 with a purge gas flow of 2.2 l/min. Initially, the release of volatile components caused a mass loss of 47.1 mg. After stabilization, water vapor was introduced at 0.4 ml/min, initiating the coal gasification reaction. The sample showed a continuous mass decrease until complete conversion, resulting in a total mass loss of 428.0 mg. This experiment highlights the suitability of the system for kinetic investigations under high-pressure and reactive conditions.
