STA PT 1600

Simultaneous Thermogravimetry (TG – DSC/DTA) – High Pressure ability

Description

On point

The STA PT1600 is the high end Simultaneous Thermobalance from LINSEIS. The system offers unparalleled TG and DSC resolution in combination with the highest vacuum capabilities and TG drift stability. The system is modular with many exchangeable furnaces (-150°C up to 2400°C), different measuring systems and crucibles. The coupling ability and many optional accessories guarantee the perfect setup for every application.

Benefits of the vertical top loading design
The vertical “sample on top” design of the LINSEIS thermobalance provides highest possible accuracy due to a stable position of the sample and easy sample handling.

Vertical system (sample on top)- LINSEIS configuration
Advantages:
• Easy sample handling
• Easy exchange of sample holder
• Stable position of the sample in the furnace
(critical for good DTA/DSC and Cp results)

Disadvantage:
• Complicated construction

Software

All LINSEIS thermo analytical instruments are PC controlled. The individual software modules exclusively run under Microsoft® Windows® operating systems. The complete software consists of 3 modules: temperature control, data acquisition and data evaluation. The 32 bit software incorporates all essential features for measurement preparation, execution, and evaluation of a STA measurement. Thanks to our specialists and application experts, LINSEIS was able to develop comprehensive easy to understand user friendly application software.

Applications

Applications example: Decomposition of Calcium Oxalate monohydrate CaC2O4 under Argon Atmosphere

The evolved gases from the decomposition of Calcium Oxalate have been fed into the Mass Spectrometer with a heated capillary. The ion currents for mass numbers 18 (water), 28 (carbon monoxide) and 44 (carbon dioxide) have been imported into the graph.
