Who runs the TGA in Australia?
the Australian Government Department of Health
The Therapeutic Goods Administration (TGA) is part of the Australian Government Department of Health , and is responsible for regulating therapeutic goods including prescription medicines, vaccines, sunscreens, vitamins and minerals, medical devices, blood and blood products.
What is thermogravimetric analysis used for?
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.
Where is TGA based?
Canberra
Our main office is located in Canberra in the suburb of Symonston.
Is the TGA government funded?
The TGA is part of the Australian Government Department of Health. It is largely self-funded and operates on a cost recovery basis. The TGA charges fees for services (such as evaluating a new product) and imposes annual charges on industry.
Is the TGA funded by Pharma?
When licensing drugs for marketing the TGA relies on research funded and controlled by pharmaceutical companies.
What is the theory of thermogravimetry?
Definitions of Thermogravimetry (TG) A technique in which the mass of the sample is monitored against time or temperature while the temperature of the sample, in a specified atmosphere, is programmed. * This is definition of TG by ICTAC.
How many types of thermogravimetry are there?
three types
There are three types of thermogravimetric analyzers: suspension system, top-loading system and horizontal system.
Who funds the TGA?
Is the TGA independent of government?
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.
Can I trust the TGA?
‘The TGA has a strong reputation for being expert, independent and rigorous in its assessments of new products, and is similarly rigorous in its assessment of the safety of vaccines, so as to improve and protect the health of all Australians.
What is TGA and DTG?
TGA tells about the amount of materials removed in % against temperature, while DTG tells about the rate at which these materials are removed in %/min, and it’s depicted be either exo or endothermic peak.
What is difference between TGA and DSC?
Differential Scanning Calorimetry can track the changes in the heat flow to and from a sample as the temperature is changed in a controlled manner….
| TGA | DSC | |
|---|---|---|
| Analysis Environment | Inert (nitrogen flow), or oxidizing (air flow) | Inert (nitrogen flow), or oxidizing (air flow) |
What are the common atmospheres employed in thermogravimetry?
The thermal reaction may occur under a variety of atmospheres including: ambient air, vacuum, inert gas, oxidising/reducing gases, corrosive gases, carburising gases, vapours of liquids or “self-generated atmosphere”; as well as a variety of pressures including: a high vacuum, high pressure, constant pressure, or a …
Can you trust the TGA?
Across our two surveys we received almost 4,000 responses, which included a representative sample of 1,045 Australian consumers. Of the consumers in the representative sample who had heard of the TGA, 75% agreed that the TGA can be trusted to perform its role ethically and with integrity.
Did the TGA approve thalidomide?
The company received a positive decision from the TGA in October this year. TGA approves thalidomide for myeloma. “I think they wanted a high-quality, tightly controlled product as soon as possible,” says Steve Slack, General Manager of Pharmion.
Is the TGA funded by pharmaceutical companies?
What is DTA and DTG?
DTG will provide you the percentage and peak temperature of sample mass change. DSC will provide you heat flow variation in milli watt/micro watt; and DTA will provide you heat flow measured in micro volt/ delta Temperature/Temperature per milli gram.
What is TGA DSC and DTA?
TGA, DTA, and DSC are three terms used to describe the analysis of compounds that take part in chemical reactions using changes in temperature of these compounds. TGA stands for Thermal Gravimetric Analysis, and DTA stands for Differential Thermal Analysis while DSC stands for Differential Scanning Calorimetry.
What is DTA and DSC?
Differential thermal analysis (DTA) is suited for the determination of characteristic temperatures, while differential scanning calorimetry (DSC) additionally allows for the determination of caloric values such as the heat of fusion or heat of crystallisation.
Which is the type of sample holder in thermogravimetry?
The size and shape of sample holder depend on the nature, weight of sample and maximum temperature range to be employed. The materials for construction of sample holders are glass, quartz alumina, stainless steel, graphite, platinum etc. sample holders are of following types.
What is the meaning of thermogravimetry?
Definition of thermogravimetry. : the determination (as with a thermobalance) of weight changes in a substance at a high temperature or during a gradual increase in temperature.
What is a thermogravimetric analyzer?
The Thermogravimetric Analyzer. Thermogravimetric analysis (TGA) is conducted on an instrument referred to as a thermogravimetric analyzer. A thermogravimetric analyzer continuously measures mass while the temperature of a sample is changed over time.
What is the significance of thermogravimetric analysis (TGA) for 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 are the different types of thermogravimetry?
There are three types of thermogravimetry: Isothermal or static thermogravimetry: In this technique, the sample weight is recorded as a function of time at constant temperature.
