STA PT1600 TG-DSC/DTA (STA Simultaneous Thermal Analysis)
Simultaneous Thermogravimetry - Differential Scanning Calorimetry - STA (TG - DSC/DTA) - High Pressure ability
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)
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.

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.
The main parts of cement are tri calcium silicate, di calcium silicate and tri calcium aluminates. Hydrates slowly form after mixing cement with water. The absorbed water evaporates first. Hydrates of the calcium silicate decompose at 570°C. The hydroxides of calcium, magnesium and aluminum follow. Subsequently, CO2 splits off from calcium carbonate.
Here is a short extract about our available accessories:
- Software for determination of calculated DTA signal
- Different types of vacuum and turbo molecular pumps
- Selection of manual, semi-automatic and automatic (MFC) Gas control boxes
- Broad range of crucibles (gold, silver, platinum, quartz glass, alumina oxide, aluminum, high pressure stainless steel, etc.)
- different measuring systems
- Optional Evolved Gas Analysis (EGA)
Vacuum and controlled atmosphere
The balance design provide for high vacuum, inert, reducing, oxidiz ing or humidified atmosphere. Furthermore, the instrument can be pressurized up to 5 bar overpressure (option). Certain corrosive conditions can be analyzed with proper precautions. The system is capable of adapting residual gas analysis systems using an optional heated capillary.
Evolved gas analysis
Optional gas analysis with MS, FTIR or GCMS is possible. This provides valuable additional information.
Our STA PT 1000 and 1600 can be equiped with a proven sample robot for unattended sample measurements.
Wide temperature range -150 to 2400°C
The LINSEIS STA instruments can be equipped with up to three furnaces at the same time. A broad variety of different furnaces is available to enable measurements in the widest temperature range on the market. Unmatched selection of furnaces for widest possible temperature range.
The starter kit includes a variety of tool such as scissors, cutting tools, anti electrostatic tweezers, magnifier, crucible holder, pipette, rasps, spatula etc.
Oxygen Getter Material OGM
The LINSEIS oxygen getter system (OGM) can be placed in any LINSEIS system as a modification of the sample gas capillary. It is used to getter smallest traces of residual oxygen in the sample chamber by offering a stronger oxygen affinity than sample materials, combined with a high effective surface to ensure the oxygen molecules react with the getter before they have a chance to get in touch with the sample. Especially for oxidation sensitive samples, where hydrogen gas mixtures can’t be used or very small enthalpy signals are expected, the OGM is a very effective and easy to use solution. With its modular character, it can be used for special experiments and can be easily removed for measurements under air or where the oxygen content is less important.
