Thermogravimetric analysis or thermal gravimetric analysis (TGA) is a method of thermal analysis in which the mass of a sample is measured over time as the temperature changes. . 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 ...
Thioglycolic acid (TGA) is the organic compound HSCH 2 CO 2 H. TGA is often called mercaptoacetic acid (MAA). It contains both a thiol ( mercaptan ) and carboxylic acid functional groups. It is a colorless liquid with a strongly unpleasant odor .

Chemical testing might have a variety of purposes, such as to: Determine if, or verify that, the requirements of a specification, regulation, or contract are met; Decide if a new product development program is on track: Demonstrate proof of concept
Polymers represent another large area in which thermal analysis finds strong applications. Thermoplastic polymers are commonly found in everyday packaging and household items, but for the analysis of the raw materials, effects of the many additive used (including stabilisers and colours) and fine-tuning of the moulding or extrusion processing used can be achieved by using differential scanning ...
A test should be invariant between relevant subgroups (e.g., demographic groups) within a larger population. [6] For example, for a test to be used in the United Kingdom, the test and its items should have approximately the same meaning for British males and females.
The presence of copper in this qualitative analysis is indicated by the bluish-green color of the flame. Although modern analytical chemistry is dominated by sophisticated instrumentation, the roots of analytical chemistry and some of the principles used in modern instruments are from traditional techniques, many of which are still used today.
Evolved gas analysis (EGA) is a method used to study the gas evolved from a heated sample that undergoes decomposition or desorption. It is either possible just to detect evolved gases using evolved gas detection (EGD) or to analyse explicitly which gases evolved using evolved gas analysis (EGA). [ 1 ]
