Thermogravimetric Analyzer BXT-TGA-101

A thermogravimetric analyzer (TGA) is an instrument that measures the weight change of a sample during heating, cooling, or isothermal processes.

Drawell’s TGA instrument consists of three main parts:

  • a high-precision 0.1 μg microbalance,
  • a programmable temperature furnace ranging from room temperature to 1250 degrees Celsius,
  • a control system that can be supplied with nitrogen, air, argon, or other special gas atmospheres.

Features of BXT-TGA-101 TGA

  1. Internal calibration ensures accuracy and repeatability.
  2. Imported alloy sensor: corrosion-resistant, anti-oxidation, high sensitivity.
  3. Precious metal alloy wire heating reduces interference and withstands high temperatures.
  4. Perfect atmosphere control with automatic software parameter switching; data directly recorded in database.
  5. ARM Cortex-M3 controller enables faster operation and precise temperature control.
  6. Bidirectional USB for intelligent operation.
  7. inch 7-bit color LCD touchscreen displays real-time status.
  8. Top lid opening for easy use; however, moving oven body upwards for sample placement is difficult and risks damaging sampling rod.
  9. Automated test report generation and printing: integrated software for recording, processing, and formatting.

TGA Coupled Analysis

For more in-depth analysis of the released gas composition, TGA analyzers are often coupled with the following instruments:

  • TGA-FTIR (Temporal-to-Infrared Spectroscopy): Real-time identification of the chemical structure of the released gas.
  • TGA-MS (Mass Spectrometry): Detection of the molecular weight of the released gas.
  • TGA-GC/MS: Collection of the released gas for offline or online chromatographic analysis.
