TGA PT 1000

Cost effective Thermobalance


On point

The Linseis TGA PT1000, designed for thermogravimetric applications, is a top-loading thermobalance known for its user-friendly design. It offers electronic taring, even with sample weights of up to 5 grams.

The specially engineered furnaces are capable of achieving rapid heating and cooling rates ranging from 0.001 to 250°C per minute, while providing highly precise temperature control from room temperature (RT) up to 1100°C.

Optionally, the system can be equipped with a coupling device for Evolved Gas Analysis (EGA). This instrument is particularly well-suited for conducting studies related to thermal composition, thermal stability, and oxidation.

Additionally, an optional calculated DTA (Differential Thermal Analysis) signal provides valuable supplementary information concerning endothermal or exothermal reactions and can serve as a tool for temperature calibration.

Linseis Automation System:

For extended, unattended operation, an optional 42-position sample robot can be combined with the optional automatic gas control and automatic evacuating system.

For even greater throughput, a sample robot with a capacity of up to 84 positions is also available.

TG – Features:

  1. Mass change as % and mg: The software can display mass changes both as a percentage and in milligrams, making it versatile for different types of measurements.
  2. Rate-Controlled Mass Loss: It supports the evaluation of rate-controlled mass loss, which is essential for understanding the kinetics of a sample’s decomposition or other thermal events.
  3. Evaluation of mass loss: The software can analyze and present data related to mass loss during a thermogravimetric measurement.
  4. Residue mass evaluation: It includes tools for evaluating the residue mass, which can be crucial in understanding the composition of a sample after thermal analysis.

General Features:

  1. Program capable of text editing: The software is equipped with text editing capabilities, which can be useful for adding annotations or notes to your measurements.
  2. Data security in case of power failure: It appears to have mechanisms in place to protect data in case of a power failure, ensuring data integrity and preventing loss.
  3. Thermocouple break protection: This feature likely safeguards against issues related to thermocouple breakage during measurements.
  4. Repetition measurements with minimum parameter input: It seems to support repeating measurements with minimal input of parameters, which can save time and reduce errors.
  5. Evaluation of current measurement: The software can evaluate the ongoing measurement, providing real-time data analysis.
  6. Curve comparison up to 32 curves: It allows you to compare and overlay up to 32 different curves, which can be useful for comparative analysis.
  7. Storage and export of evaluations: You can save and export evaluation data, enabling you to share or store the results as needed.
  8. Export and import of data in ASCII format: The software supports exporting and importing data in ASCII format, enhancing data interoperability.
  9. Data export to MS Excel: You can export data directly to Microsoft Excel, making it easier to work with data in a familiar spreadsheet format.
  10. Multi-methods analysis (DSC TG, TMA, DIL, etc.): It seems to support various thermal analysis techniques, including Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TG), Thermomechanical Analysis (TMA), and Dilatometry (DIL).
  11. Zoom function: The software includes a zoom function, which is beneficial for detailed examination of specific sections of your data.
  12. 1 and 2 derivation: Derivative analysis is included, allowing you to analyze the first and second derivatives of your data.

  15. Free scaling, rewrite the content: This feature allows you to scale and edit the content as needed, providing flexibility in your analysis and reporting.

These features collectively contribute to the versatility and functionality of the LINSEIS thermo analytical software, making it a comprehensive tool for thermal analysis and data evaluation.


Applications example: Decomposition of CaC2O4 • H2O

The gases produced during the decomposition of calcium oxalate were introduced into a mass spectrometer using a heated capillary. The ion currents corresponding to mass numbers 18 (representing water), 28 (representing carbon monoxide), and 44 (representing carbon dioxide) have been recorded and plotted on a graph.

Applications example: Cement

The primary components of cement consist of tricalcium silicate, dicalcium silicate, and tricalcium aluminates. Upon mixing cement with water, the hydration process occurs gradually. Initially, the absorbed water evaporates. The hydrates of calcium silicate break down at around 570°C. Following this, the hydroxides of calcium, magnesium, and aluminum go through a similar process. Subsequently, carbon dioxide is released from calcium carbonate.

Applications example: Decomposition of rubber

The weight loss process occurs in several steps. First, there is the dehydration of the sample, which results in a loss of 9.27% due to the removal of water. In the second step, carried out under a nitrogen (N2) atmosphere, the volatile components are released through pyrolysis, leading to a weight loss of 35.99%. In the third step, the atmosphere is changed to oxygen (O2), and all organic components are burned away, resulting in a weight loss of 14.33%. The remaining 40.41% of the sample consists of inorganic components such as ashes, slake, or fillers.

Applications example: Aspirin

As the heating process initiates, there is an initial loss of weight of approximately 1% due to the release of adsorbed water. When the temperature reaches 140°C, the melting point of the Aspirin is attained, causing an exothermic reaction that is detected on the DTA trace. At 160°C, the melted drug undergoes decomposition in multiple stages. Since the resulting decomposition products are volatile, there is a substantial weight loss of around 80%.
