Thermogravimetric and Differential Thermal Analysis

Thermogravimetric and Differential Thermal Analysis (TG-DTA)

TG/DTA: Technique to measure material mass change when exposed to temperature.

Differential Thermal Gravimetric Analysis

Thermal Analysis is a branch of science that deals with the changes in the property of the material. When heated, melted, or decomposed, the material will change its state. There are many methods on which it is done, and when it is done on heating, it is known as Thermogravimetric Analysis (TG). The process is go through in a controlled atmosphere. The function of mass change used in TG is temperature or time. The technique is useful for decomposition, dehydration, desorption, and oxidation. There are multiple applications of TGA. It also measures the thermal stability of the material along with determining the volatile components. It is subject to under heating under temperature heating and a predetermined heating rate.

Differential Thermal Analysis (DTA)

Out of multiple thermal methods of analysis, the most widely used is Differential Thermal Analysis (DTA). In this technique, the temperature of the material is compared with inert reference material. It is carried out in an atmosphere of programmed change of temperature that means they are made to undergo an identical thermal cycle. When there is change in the energy (either chemical/physical phenomenon), the difference in the temperature of both the materials identifies the transition. Also, DTA experiments are done at a specific temperature, but the user is not known what’s happening.

Interpreting The Results
To reach the results in the best way, other methods are also needed. Mostly X-ray diffraction, spectroscopy, composition analysis, microscopic investigation, electron probe microanalysis, etc.

TG Combined With DTA

The major difference between these approaches is that TG only measures that occurs due to mass loss. On the other hand, DTA also considers the change where no mass is lost. For example, glass transition, crystal structure changes, melting, etc.

Metallic block, a furnace, thermocouples, sample containers, temperature programmer, ceramic block, and recording systems. These are components of the list of apparatus required to effectively carry out TG/DTA experiments. Nishka Research is a company that deals with technical and research-related work for years.

I am a PhD scholar from Kaunas University at Lithuania, Europe. I have given a sample to perform SEM analysis of the organic tissue. The results are highly satisfactory and impressive. The service was really excellent, on time( even before the time schedule), consumer friendly. cost to the academic samples are very less comparing with others. Once again thanks to Nishka for providing me the service ontime as I am really in urgency...
