What do I do with Simultaneous Thermal Analyzer (TG-DSC) test data and results?
Synchronous Thermal Analyzer (TG-DSC) is a high-precision experimental equipment used to measure the mass change and heat flux change of materials during heating or cooling, and processing the Synchronous Thermal Analyzer (TG-DSC) test data and results is a key step in the experimental process.
1. Data collection.
In the process of synchronous thermal analyzer (TG-DSC) experiment, it is first necessary to set the experimental parameters according to the experimental purpose and sample characteristics, such as heating rate, temperature range, etcDuring the experiment, the synchronous thermal analyzer (TG-DSC) automatically collects the data of mass change and heat flow change, and after the data collection is completed, the data needs to be transferred to the computer for analysis.
2. Data preprocessing.
1.Data cleaning: Due to the interference of various factors during the experiment, such as instrument error, improper sample preparation, etc., the original data needs to be cleaned to remove abnormal data and noise.
2.Data Conversion: Convert raw data into analytical-ready formats such as peak area, peak height, and more.
3.Baseline correction: Baseline correction is performed on quality change data to eliminate baseline drift during the experiment.
3. Data analysis.
1.Peak detection: According to the experimental purpose and sample characteristics, determine the peak position, peak area, peak height and other parameters.
2.Phase change point determination: Determine the location and temperature of the phase change point based on the data of mass change and heat flux change.
3.Thermal effect calculation: According to the heat flux change data, the thermal effect parameters such as phase change heat and reaction heat are calculated.
4.Thermal stability analysis: Analyze the thermal stability of the sample during heating or cooling, such as thermal decomposition temperature, melting point, etc.
5.Kinetic analysis: Analyze the rate of chemical reactions or physical changes based on parameters such as peak area and peak height.
4. Verification and reporting of results.
1.Verification of results: Verify the accuracy of the results of the Synchronous Thermal Analyzer (TG-DSC) by comparing the results with other experimental methods (e.g., DSC, XRD, etc.).
2.Report writing: Write a detailed experimental report according to the experimental purpose, data analysis and result verification, including experimental methods, data analysis, and result discussion.
5. Data processing software.
Synchronous thermal analyzers (TG-DSCs) are usually equipped with data processing software that can be used for data acquisition, cleaning, conversion, analysis, and other operationsWhen processing data, it is necessary to make full use of the functions of the software to ensure the accuracy and efficiency of data processing.
6. Precautions for experiments.
1.Sample preparation: Ensure that the sample preparation is uniform and pure, and avoid impurities or agglomerates in the sample, which will affect the experimental results.
2.Experimental parameter setting: According to the characteristics of the sample and the purpose of the experiment, the experimental parameters should be set reasonably, such as the heating rate, temperature range, etc.
3.Instrument calibration: Calibrate the Synchronous Thermal Analyzer (TG-DSC) regularly to ensure the accuracy and stability of the instrument.
4.Data collection: During the experiment, it is necessary to ensure the continuity and integrity of data collection to avoid missing important data.
5.Result analysis: Make full use of the data processing software and analysis methods of the synchronous thermal analyzer (TG-DSC) to accurately interpret the experimental results.
