What can TGA tell you?
What can TGA tell you?
What TGA Can Tell You? Weight Loss: – Decomposition: The breaking apart of chemical bonds. – Evaporation: The loss of volatiles with elevated temperature. – Reduction: Interaction of sample to a reducing atmosphere (hydrogen, ammonia, etc).
How does TGA calculate mass loss?
2- Any part of the inorganic is not removed due to the thermal treatment. If these conditions are satisfied, you can calculate the: – The mass of the polymer= total weight of your composite * weight loss % from TGA). – The mass of the filler= total weight of the composite* (1-weight loss % from TGA).
What is TGA analysis of polymers?
Thermogravimetric analysis (TGA) of polymers is conducted to measure weight changes as a function of temperature and time. The weight changes of polymeric materials can be caused by decomposition and oxidation reactions as well as physical processes such as sublimation, vaporization, and desorption.
What is TGA FTIR?
TGA measures the change in sample weight as a function of temperature or time in a controlled atmosphere, which is usually accompanied by an evolution of gases caused by sample decomposition or volatilization. …
Why is TGA important?
The TGA is responsible for regulating therapeutic goods including medicines, medical devices, blood and blood products. What are ‘therapeutic goods’? Many of us use medicines or medical devices in our daily lives.
What is a TGA machine?
The Thermogravimetric Analyzer (TGA) is an essential laboratory tool used for material characterization. TGA is used as a technique to characterize materials used in various environmental, food, pharmaceutical, and petrochemical applications.
Why TGA is done?
TGA can be used to evaluate the thermal stability of a material. TGA is used in the analysis of polymers. Polymers usually melt before they decompose, thus TGA is mainly used to investigate the thermal stability of polymers. Most polymers melt or degrade before 200 °C.
What is FTIR analysis used for?
FTIR spectroscopy is used to quickly and definitively identify compounds such as compounded plastics, blends, fillers, paints, rubbers, coatings, resins, and adhesives. It can be applied across all phases of the product lifecycle including design, manufacture, and failure analysis.
Why was the TGA created?
The Therapeutic Goods Administration (TGA), as part of the Australian Government Department of Health, was established in 1989 and protects the health and wellbeing of the community by regulating and monitoring all therapeutic goods that are distributed here in Australia.
What is a TGA-MS measurement?
TGA-MS measurements open up a wide range of new application possibilities both for mass spectrometry and for TGA compared with when the techniques are used alone. To obtain the best results, the effects of a number of different experimental parameters have to be taken into account.
What isthermogravimetric analysis (TGA)?
Thermogravimetric Analysis (TGA) measures changes in weight of a sample with increasing temperature. Measurements are used primarily to determine the composition of materials and to predict their thermal and oxidative stability.
What is the significance of TGA in thermal stability studies?
The changes in sample weight (mass) can be a result of alterations in chemical or physical properties and can be detected to a fraction of a microgram. TGA is useful for investigating thermal stability of solid or liquid materials under conditions of ramping temperature in an inert gas atmosphere or in an oxidative gas atmosphere.
What is the purpose of using TGA?
TGA is useful for investigating thermal stability of solid or liquid materials under conditions of ramping temperature in an inert gas atmosphere or in an oxidative gas atmosphere. TGA can also be conducted at constant temperature to evaluate thermal stability of materials over a specific time period.
