Product Details

TGA 5500Thermogravimetric analysis (TGA)Integrating high-level performance and functionality into one, easily meeting the needs of researchers. TGA 5500 aims to achieve a wide range of temperature control while minimizing drift (drift lower than any competing TGA products, even those that use post test data processing). TA proprietary infrared heating furnace * has fast heating and cooling rates. The new automatic sampler has set high productivity standards.

Thermogravimetric analysis (TGA)Specific principle:

1. Heating process: The sample is placed in a microbalance, usually connected to a heating furnace. The furnace temperature gradually increases, and the sample temperature rises with the increase of furnace temperature.

2. Quality measurement: The mass changes of the sample at different temperatures are recorded in real-time by the balance. The decrease in quality usually means that the sample has undergone some chemical changes at high temperatures, such as dehydration, desolvation, decomposition, or oxidation.

3. Data analysis: By analyzing the relationship between quality changes and temperature changes, the thermal decomposition temperature, decomposition rate, and other thermal stability data of the material can be obtained.

The operation steps of TGA experiment:

1. Sample preparation: Firstly, it is necessary to prepare the sample to be tested. The size, shape, and quality of the sample should be adjusted according to the experimental requirements. Generally speaking, samples should have a certain degree of uniformity to ensure the accuracy of test results.

2. Equipment debugging: Start the TGA equipment, set the appropriate experimental temperature range, heating rate, and experimental atmosphere (such as nitrogen, air, etc.). Usually, the test is preheated at room temperature and then gradually heated up.

3. Data collection: As the temperature increases, TGA equipment records real-time changes in sample quality and generates a mass temperature curve. According to the different stages of quality changes, the equipment can generate different thermal decomposition process diagrams.

4. Data analysis: After completing the test, the stability characteristics of the sample at different temperatures can be obtained by analyzing the quality temperature curve. Common analysis methods include calculating weight loss rate, decomposition temperature, etc.

Thermogravimetric analysis (TGA)Advantages:

1. High sensitivity: TGA can detect extremely small changes in mass, suitable for high-precision analysis.

2. Multifunctionality: In addition to measuring thermal stability, TGA can also be used to analyze the composition, decomposition behavior, and reactivity during pyrolysis of materials.

3. Wide application: Due to its efficient thermal analysis capability, TGA is widely used in various scientific research and industrial fields, such as materials science, chemical engineering, environmental monitoring, etc.
