Thermogravimetric analysis (TGA) is a technique used to measure changes in sample weight as a function of temperature or time. This technique is valuable because even small changes in a sample's weight can provide a wealth of information about its chemical and physical properties. The sensitivity and quality of the balance used in TGA allows for precise measurements of even small changes in sample weight, enabling researchers to gain insight into various phenomena that affect the sample, such as vaporization, sublimation, absorption, adsorption, and desorption.
