TA Instruments TGA-5500 Discovery


Available Methods and Accessories

  • Weight loss vs temperature/time
  • Modulated TGA
  • High Resolution Hi-Res TGA
  • Step Isothermal TGA

Sample Requirements

  • The balance can handle samples up to 100 mg in mass although a standard operating mass is 5- 20 mg.

Detection Limits

  • Temperature Range: Ambient to 1200°C
  • Isothermal Temp Accuracy +/- 1°C
  • Controlled Heating Rate 0.1 to 500 °C/min
  • Weighing Precision +/- 0.01%

Summary of Technique

  • Thermogravimetric Analysis (TGA) is a technique in which the mass of a substance is monitored as a function of temperature or time as the sample specimen is subjected to a controlled temperature program in a controlled atmosphere.
  • A TGA consists of a sample pan that is supported by a precision balance. That pan resides in a furnace and is heated or cooled during the experiment. The mass of the sample is monitored during the experiment. A sample purge gas controls the sample environment. This gas may be inert or a reactive gas that flows over the sample and exits through an exhaust

Information Provided & Detection Limits

  • TA instrument TGA-5500 Discovery is ideally for the measurement of weight change with temperature for compositional analysis of multi-component system, thermal oxidative stability, activation energy, effects of reactive atmosphere, decomposition kinetics, and quantification of identified components.
  • Determines the moisture content of polymers and related materials.
  • It offers precise temperature control for linear and modulated heating rates from 0.1 to 500°C/min to resolve complex and weak material transitions.
  • Samples can be tested in an inert environment (N2 or Ar) or in air/oxygen.
  • A 25- position auto- sampler with a contamination-free sealed pan punching system, provides efficient, accurate and reliable TGA results possible.
