GSA PT 10

Fast and reliable measurements

Description

To the point

Our GSA PT 10 series is based on the proven standard design of the Linseis microbalance.
This ultra-sensitive microbalance is available in two versions with 0.1/1ug and 5 / 25 / 35g initial weights.

You can also choose from a wide range of furnaces for measurements from -150 to 1600 °C and UHV (ultra-high vacuum) up to 10 bar.

An optional TG-DSC (Thermogravimetry – Differential Scanning Calorimetry) sensor enables the simultaneous determination of weight change and caloric reaction in one measuring run.
Optional gas and vapor dosing systems as well as measuring devices for residual gas analysis are also available.

Usable vapors and gases are for example: Alcohols, hydrocarbons, aromatics, hydrogen, water, oxygen, nitrogen, argon, carbon dioxide, etc.

Software

Making values visible and comparable

The powerful LINSEIS thermal analysis software, which is based on Microsoft® Windows®, performs the most important function in the preparation, execution and evaluation of thermoanalytical experiments, in addition to the hardware used.
With this software package, Linseis offers a comprehensive solution for programming all device-specific settings and control functions, as well as for data storage and evaluation.
The package was developed by our in-house software specialists and application experts and has been tried and tested over many years.

Applications

Application example: Desorption of hydrogen from TiH2

Titanium hydride is a common used hydrogen resource for controlled release of hydrogen in various reactions. On the one hand it can be used as a catalyst in liquid chemistry in situ as a hydrogen source, on the other hand it can be used for example in batteries or fuel cells for controlled hydrogen release.  To get an idea what amount of hydrogen is released at what temperature, it is important to know the temperature dependent decomposition behavior and released amount of heat, which can be monitored by simultaneous thermal analysis (STA).

In this STA measurement, the release of hydrogen by titanium hydride was monitored. TG and DSC signal were measured from Room Temperature to 800°C while the sample was heated linear in Argon atmosphere with 10K/min. Between 300°C and 600°C, there is a two-step mass loss of 2.3% in total which means the complete amount of bound hydrogen is released in that process. The DSC curve shows the corresponding Desorption peaks (red curve).
