The working principle and analysis method of thermogravimetric analyzer

Thermogravimetric analyzer is mainly composed of balance, furnace, program temperature control system, recording system and so on. There are two commonly used measurement principles, namely displacement method and zero method. The so-called displacement method is based on the proportional relationship between the tilt of the balance beam and the mass change, and the tilt is detected with a differential transformer and automatically recorded. The zero method uses the differential transformer method and the optical method to measure the tilt of [...]

How to choose the right thermogravimetric analyzer

Thermogravimetric analyzer (TGA) is a kind of instrument used to detect the relationship between temperature and mass of a substance. Thermogravimetry is to measure the mass of a substance with temperature (or time) under programmed temperature control. When the substance under test sublimates, vaporizes, breaks down gas or loses crystal water during heating, the mass of the substance under test will change. У овом случају, the thermogravimetric curve is not a straight line but a decline. By analyzing the thermogravimetric [...]
