Influencing Factors of Thermogravimetric Analyzer

For thermogravimetric determination, the sample amount is small, generally 2 to 5 mg. On the one hand, the sensitivity of the instrument balance is very high. On the other hand, if the sample volume is large, the greater the mass transfer resistance, the greater the temperature gradient inside the sample, and even the thermal effect of the sample will cause the sample temperature to deviate from the linear heating program, thereby changing TG curve. The finer the particle size, the better. If the particle size is large, the decomposition reaction will shift to high temperature. The material of the sample tray should be high temperature resistant and inert to the sample, intermediate products, products and the atmosphere, that is, it cannot have reactivity and catalytic activity. Commonly used sample pans include platinum, ceramics, quartz, glass, aluminum and so on. It is important to note that different samples should use sample pans of different materials, otherwise the sample pan will be damaged. For alkaline samples, such as sodium carbonate, aluminum, quartz, glass and ceramic sample pans should not be used for testing. The platinum sample pan is not suitable for polymer samples containing phosphorus, sulfur, and halogens because it is active against hydrogenated or dehydrogenated organic compounds.
