STA PT 1600 (TG-DSC)

Simultaneous Thermogravimetry and Differential Scanning Calorimetry (TG – DSC) – High Pressure ability


On point

The STA PT 1600 is the high end Simultaneous Thermobalance (TG+DSC) from LINSEIS. The system offers unparalleled TG and DSC resolution in combination with the highest vacuum capabilities and TG drift stability.

The TG-DSC 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.

There are three versions of balances available: they differ by the maximum sample mass (5 to 50g) and the resolution (0.025 to 0.1ug).

Benefits of the vertical top loading design of the STA

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

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

• Complicated construction

*The specifications depend on the selected furnace and special configurations

There are three different models of STA PT 1600 available:


STA PT 1600/1

The highest resolution 0.025 μg balance for small sample quantities allows the detection of very small effects with highest accuracy.

STA PT 1600/2

The standard model covers a broad application range with excellent resolution 0.1 μg and accuracy.

STA PT 1600/3

The high mass variant allows measuring samples with big volumes or weight 35/50g to determine even small effects within a big amount of inhomogeneous material.

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.
