PROBLEM TO BE SOLVED: To provide a temperature-modulated thermogravimetric analysis (TMTGA) method which analyzes a sample, using a thermogravimetric analysis (TGA) instrument.SOLUTION: The TGA instrument comprises: a furnace arranged in a furnace housing 4; an electronic balance 1 with a load receiver 3 arranged in a balance housing 2, wherein the load receiver 3 extends into the furnace housing 4 and a measuring position is arranged at one end of the load receiver 3 within the furnace housing 4; and a control unit 9 for controlling the balance and/or the furnace. The TMTGA method comprises the steps of: placing a sample 6 on a measuring position in the thermogravimetric analysis (TGA) instrument; subjecting the sample to a temperature program provided by the control unit, which varies the temperature of the furnace; measuring a change of the mass of the sample 6 as a function of time, in accordance with the temperature program; and determining at least one kinetic parameter of the sample 6 by analyzing the mass change. |
