Description

Thermogravimetric analysis (TGA) is an analytical technique used to determine a material’s thermal stability and its fraction of volatile components by monitoring the weight change that occurs as a sample is heated at a constant rate. This measurement provides information about physical phenomena, such as phase transitions, absorption, adsorption and desorption; as well as chemical phenomena including chemisorptions, thermal decomposition, and solid-gas reactions (e.g., oxidation or reduction). The performance of the TGA-Q500 arises from a responsive low-mass furnace, ultra-sensitive thermobalance, and efficient horizontal purge gas system (with mass flow control). The TA Instruments Q500 TGA offers a high-temperature limit for thermal analysis. The instrument measures the mass loss of a sample very accurately versus temperature.

Model: TGA-Q500.

Specifications:

  • Temperature Range: 25 to 950 °C.
  • Weight measuring range: 20mg, 200mg.
  • Programmable heating rate: 0.1°C/hour to 99.9°C/min.
  • Cooling method : Air-cooled.
  • Signal output: Analog and digital.
  • Atmosphere control: Built-in gas flowmeter (250ml/min maximum)

Applications:

  • Used to measure the weight of fiberglass and inorganic fill materials in plastics, laminates, paints, primers, and composite materials by burning off the polymer resin.
  • Can measure the fill materials added to some foods.
  • Can determine the purity of a mineral, inorganic compound, or organic material.
  • Distinguishes different mineral compositions from broad mineral types, such as borax, boric acid, and silica gels.
  • Can be used to measure evaporation rates as a function of temperature, such as to measure the volatile emissions of liquid mixtures.

Sample:

  • The sample size: 50 mg.
