Differential Thermogravimetric Analysis Principles, Applications and Solutions | SKZ

Differential Thermogravimetric Analysis (DTG) is an analytical method that measures the mass change rate of a substance under programmed temperature control. Its core principle is to differentiate the weight loss curve recorded in thermogravimetric analysis (TGA) with respect to time or temperature to obtain a curve showing the relationship between the mass loss rate (dm/dt) and temperature.

Key Features of DTG

1

Directly display the peak temperature of material decomposition and accurately locate thermal events (such as decomposition and oxidation).

2

Can distinguish overlapping thermogravimetric processes (such as staged decomposition of multi-component materials).

3

Combined with TGA, complex thermal reaction mechanisms can be interpreted more intuitively.

Why choose DTG?

Compared to traditional TGA, DTG eliminates the interference of baseline drift through differential processing, which is particularly suitable for analyzing trace samples or multi-stage decomposition reactions. It is an important tool in the fields of materials science and chemical research.

Main application areas of DTG


DTG technology is widely used in the following scenarios due to its high sensitivity and accuracy:

1.Materials Science

Analyze the thermal stability of polymer materials (such as the decomposition temperature of plastics and rubber).
Determine the decomposition ratio of each component in the composite material.

2. Pharmaceutical Industry

Detect the purity and decomposition behavior of active ingredients of drugs.
Evaluate the compatibility of drug excipients with the main ingredients.

3. Environmental Science

Study the combustion characteristics of biomass (such as the pyrolysis behavior of straw and waste).
Analyze the thermal degradation process of pollutants (such as microplastics).

4. Energy Field

Optimize the thermal stability of battery materials (such as lithium-ion battery electrode materials).
Evaluate fuel combustion efficiency and residual composition.

FAQ

Does the DTG instrument need to be calibrated regularly?

Yes, the DTG instrument needs to be calibrated regularly to ensure data accuracy. It is recommended to calibrate once every 6 months, or adjust the calibration cycle according to the frequency of use. We provide free calibration training and technical support to help users complete calibration easily.
DTG testing usually requires a sample volume of 0.1mg~200mg, depending on the instrument model and test requirements. High-sensitivity sensors are required for trace sample testing to ensure data reliability.

Module 3: Technical advantages and challenges of DTG

Technical advantages:
✅ High resolution: can clearly separate adjacent thermal weight loss peaks and accurately identify complex reaction steps.
✅ Quantitative analysis: calculate weight loss ratio by peak area, support multi-component quantitative research.
✅ High sensitivity: suitable for trace samples (as low as milligram level), saving experimental costs.

Common challenges:
⚠️ Complex data analysis: need to combine TGA original curve and DTG peak shape for comprehensive judgment.
⚠️ High instrument calibration requirements: temperature accuracy and baseline stability directly affect the reliability of results.
⚠️ High equipment cost: the purchase and maintenance costs of high-end DTG instruments may become a burden for small and medium-sized laboratories.

Our solution: provide intelligent data analysis software and free calibration training to help users quickly get started and optimize experimental results.
