  • TGA 1000/1200/1500

FEATURES

  • Proprietary Microbalance
  • The proprietary TGA microbalance combines high sensitivity, low drift technology, and thermal insulation design to deliver exceptional weighing accuracy. With a resolution as precise as 0.1 μg, it is ideal for high-precision measurements of trace samples. The low-drift technology minimizes the impact of environmental factors, ensuring stable data even in long-duration experiments, while reducing errors caused by drift. Additionally, the thermal insulation design protects the balance from external temperature fluctuations, maintaining internal temperature stability and ensuring reliable results, even in conditions of rapid temperature change or high heat.
  • Miniature Furnace
  • The compact heating furnace is designed to significantly minimize gas buoyancy effects, ensuring that dynamic curve drift in TGA remains under 25 μg without requiring additional blank tests. Additionally, the furnace delivers a rapid temperature response, achieving heating rates of up to 300°C/min, which dramatically shortens experimental time and enhances overall work efficiency.
  • Precise Temperature Control
  • The advanced heating technology combined with a dual PID control system ensures precise adherence to the set temperature curve during both heating and cooling processes. With a temperature control accuracy of ±0.1°C, this system significantly reduces the influence of temperature fluctuations, delivering highly reliable experimental results.
  • Wide Temperature Range
  • Multiple furnace options are available to meet the specific temperature requirements of different materials. With a maximum temperature capability of up to 1500°C, these furnaces are designed to satisfy the rigorous demands of both experimental and industrial applications.
  • Furnace Auto-Lift System
  • The instrument is equipped with an automatic furnace lifting system, simplifying experimental operations and preventing equipment damage or safety incidents caused by improper manual handling.
  • Water Cooling System
  • The fully automated recirculating bath provides precise and continuous temperature control, which effectively and rapidly reduces the TGA furnace temperature, significantly shortening the experimental time.
  • Automatic Gas Switching Control
  • The gas selector supports one-button switching across multiple gases, accommodating up to 4 input ports. The device features an integrated design, consolidating four gas channels into a single module to meet the need for frequent gas switching during different testing processes.
  • Evolved Gas Analysis
  • TGA can be combined with other analytical instruments for online monitoring and qualitative analysis of evolved gases, such as mass spectrometers (MS) or Fourier-transform infrared spectrometers (FTIR).

APPLICATIONS

  • Typical Applications
  • Thermal Stability
  • Thermal Pyrolysis
  • Oxidation Reactions
  • Dehydration Process
  • Decomposition
  • Process Kinetics
  • Combustion Process
  • Moisture Content
  • Residue and Ash Content
  • Dynamic Baseline Drift
  • In a typical TGA test, the sample mass may increase due to the "buoyancy effect" of the gas. However, the design of the miniature heating furnace ensures that the drift of the dynamic thermogravimetric curve remains below 25 μg, eliminating the need for baseline curve subtraction.
  • Weight Loss Step Analysis
  • The analysis software enables clear observation of the weight loss ratio and corresponding temperatures at each stage of the process. For instance, the thermogravimetric curve of hydrated calcium oxalate demonstrates three distinct stages. In the first stage, bound water evaporates, producing water vapor and leaving behind calcium oxalate. In the second stage, calcium oxalate decomposes into calcium carbonate and carbon monoxide. Finally, in the third stage, calcium carbonate further breaks down into calcium oxide and carbon dioxide.
  • High-Resolution TGA
  • The high-resolution TGA technology intelligently adjusts the heating rate in response to the sample's decomposition rate,effectively separating overlapping mass loss regions and enhancing resolution. This enables the rapid collection of experimental data across a wide temperature range. The exceptional resolution achieved with this advanced technology is particularly beneficial for analyzing the mass loss curve in TGA and the first derivative signals (DTG), providing highly detailed and accurate results.
