Thermochimica Acta, 2003
A new type of rapid and automatic proximate analyzer for coal based on isothermal thermogravimetric analysis (TGA) with twin-furnace is introduced in this paper. This automatic proximate analyzer was developed by combination with some novel technologies, such as the automatic weighting method for multi-samples in a high temperature and dynamic gas flow

Experimental methods in chemical engineering: Thermogravimetric analysis—TGA
The Canadian Journal of Chemical Engineering, 2019AbstractThermogravimetric analysis (TGA) is a quantitative analytical technique that monitors the mass of a sample from 1 mg to several g as a furnace ramps temperature to as high as 1600°C under a stable or changing gas flow. The first gravimetric test was in 27 BC when Vitruvius measured limestone's change of mass as it calcined to lime.

Fast characterization of biomass fuels by thermogravimetric analysis (TGA)
Fuel, 2015A methodology is proposed based on thermogravimetric analysis, deconvolution of the DTG signal and empirical correlations for characterizing biomass fuels for boilers and combustors. This methodology allows determining accurately and in a short time the main parameters required for industrial operation, as are the higher heating value (HHV), the ...

Applications of thermogravimetric analysis (TGA) for biomass thermal characterization
2023Thermal analysis represents a group of techniques that analyse various physical and/or chemical properties of a sample as a function of temperature, during heating or cooling according to a certain temperature program. In order to obtain accurate results, the precise measurement of sample mass and temperatures are crucial.

Toxicology in Vitro, 2009
Recent work in our laboratory shows that it is possible to measure the minute weight changes of skin during exposure to chemical vapor using the thermogravimetric analysis (TGA) method. Further, the TGA weight curves can be analyzed with a two-compartment diffusion model, yielding two sets of diffusion and skin:air partition coefficients. In this study,

Water Research, 2016
For the elimination of potentially harmful micropollutants, powdered activated carbon (PAC) adsorption is applied in many wastewater treatment plants (WWTP). This holds the risk of PAC leakage into the WWTP effluent and desorption of contaminants into natural water bodies.
