Thermogravimetric Analysis (TGA) Service

Thermogravimetric analysis (TGA) is a high-precision thermal analytical technique used to measure the mass changes of a material under controlled temperature conditions. By heating a sample across a predefined temperature range and recording mass loss as a function of temperature or time, TGA provides critical insights into thermal stability, decomposition behavior, adsorption/desorption processes, and residual content.

Thermogravimetric analysis (TGA) is particularly effective for:

• Quantifying thermal decomposition temperatures and weight-loss behavior
• Evaluating material composition and optimizing formulations
• Precisely determining moisture, volatiles, fillers, and ash content
• Characterizing thermal reactivity under different atmospheres (e.g., air, nitrogen, oxygen)

 

Thanks to its sensitivity, reliability, and broad applicability, TGA is widely used across polymer science, pharmaceutical R&D, inorganic materials, coatings, catalysts, and energy materials research. MtoZ Biolabs offers high-quality Thermogravimetric Analysis (TGA) Service supported by a robust analytical platform and standardized workflows, enabling research and industrial clients to accurately understand the thermal behavior of their materials.

Case Study

Case 1: TGA-based Pyrolysis Kinetics of Lignocellulosic Biomass for Bioenergy Research

A study examining the pyrolysis behavior of rice straw, pine sawdust, and Phoenix tree leaves employed thermogravimetric analysis (TGA) to characterize thermal degradation and derive kinetic models. Biomass particle size and heating rate were found to significantly affect the onset and peak weight-loss temperatures. Additionally, ash removal and potassium ion addition modulated thermal reactivity. Using Coats–Redfern, Doyle, and Distributed Activation Energy Model (DAEM) methods, the researchers determined apparent activation energy differences across materials. This case highlights the utility of TGA in biomass fuel development and kinetic modeling.

FAQ

Q1: What types of decomposition mechanisms can TGA analyze?

TGA can assess multistep thermal events such as water evaporation, structural relaxation, additive volatilization, polymer breakdown, and residue formation. With precise mass loss tracking, it supports decomposition sequence evaluation and stability threshold definition, aiding in formulation and performance optimization.

 

Q2: Can TGA identify unknown components in a material?

Yes. When combined with FTIR or MS, thermogravimetric analysis (TGA) enables evolved gas analysis to identify additives, fillers, or byproducts—providing crucial information for formulation deconstruction and failure analysis.

 

Q3: Is Thermogravimetric Analysis (TGA) Service suitable for moist or heat-sensitive samples?

Absolutely. Our systems include isothermal and ramp modes, along with pre-drying capabilities. These allow controlled evaluation of sensitive materials, preventing sudden decomposition and improving data resolution and signal-to-noise ratios.
