WebFeb 5, 2024 · The TG-DSC and DSC curves of CIP show an endothermic peak at 268 °C (TG-DSC) and 270 °C (DSC, ΔH = 35.02 kJ mol −1) related to the drug melting, with no mass loss in TG curve. These curves show that the drug is thermally stable up to 280 °C and undergoes thermal decomposition in three consecutive mass loss steps, … WebDownload scientific diagram TG / DSC curve for DLiS crystal from publication: Growth, optical, mechanical, thermo-physical, laser damage threshold (LDT) and Z-scan studies on dilithium succinate ...
Differential scanning calorimetry - Wikipedia
WebAug 28, 2024 · Thermogravimetric analysis (TGA) and the associated differential thermal analysis (DTA) are widely used for the characterization of both as-synthesized and side-wall functionalized single walled carbon nanotubes (SWNTs). Under oxygen, SWNTs will pyrolyze leaving any inorganic residue behind. The DSC heat flow curve will deviate when the reaction with oxygen begins (the reaction being either exothermic or endothermic). Both OIT and OOT tests are used as a tools for determining the activity of antioxidants. Safety screening. DSC makes a reasonable initial safety screening tool. See more Differential scanning calorimetry (DSC) is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both … See more The basic principle underlying this technique is that when the sample undergoes a physical transformation such as phase transitions, more or less heat will need to flow to it … See more The result of a DSC experiment is a curve of heat flux versus temperature or versus time. There are two different conventions: exothermic reactions in the sample shown with a positive or negative peak, depending on the kind of technology used in the experiment. … See more The technique is widely used across a range of applications, both as a routine quality test and as a research tool. The equipment is easy to calibrate, using low melting See more There are two main types of DSC: Heat-flux DSC which measures the difference in heat flux between the sample and a reference (which gives it the alternative name Multi-Cell DSC) and Power differential DSC which measures the difference in power … See more An alternative technique, which shares much in common with DSC, is differential thermal analysis (DTA). In this technique it is the heat flow to … See more Differential scanning calorimetry can be used to measure a number of characteristic properties of a sample. Using this technique it is possible to observe fusion and crystallization events as well as glass transition temperatures Tg. DSC can also be … See more cricut maker 3 rollmesser

WebInterpreting DSC Data 3 Splitting a Curve into Segments To cut a measurement curve into segments users will need to left-click on their curve of interest, causing it to turn white. Then, users will right click on the same curve to display a menu. From this menu select the “Split Into Segments” option. The curve should now be cut into Webraw data (Figure 2-a). This data is equivalent to the DSC curve obtained by the conventional DSC measurement at constant rate heating (Figure 2-e). Next, the heat capacity component of Figure 2-c can be obtained by performing amplitude ratio calculations of the DSC signal and temperature signal using the Fourier transform same as AC calorimetry.
