Differential scanning calorimetry - Wikipedia
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 the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the temperature program for a DSC analysis is desi…
Types
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 … 展开
Detection of phase transitions
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 than the reference to maintain both at … 展开

示差扫描量热法
差示扫描量热法（differential scanning calorimetry,DSC），一种热分析法。在程序控制温度下，测量输入到试样和参比物的功率差（如以热的形式）与温度的关系。差示扫描量热仪记录到的曲线称DSC曲线，它以样品吸热或放热的速率，即热流率dH/dt（单位毫焦/秒）为纵坐标，以温度T或 …

What is the temperature program for a DSC analysis?
Generally, the temperature program for a DSC analysis is designed such that the sample holder temperature increases linearly as a function of time. The reference sample should have a well-defined heat capacity over the range of temperatures to be scanned.

What are the applications of DSC?
Calculate heat of any reaction from the given data. Explain the applications of DSC to polymeric materials and pharmaceuticals. Explain the applications of simultaneous TG-DTA-DSC analysis. Differential scanning calorimetry (DSC) has become the most widely used thermal analysis technique.

What does DSC mean in chemistry?
DSC, Differential scanning calorimetry. When the temperature rises to above the glass transition temperature, a polymer will become more mobile until it reaches the optimal temperature for crystallization to take place. The molecules will arrange themselves in an extremely ordered fashion, and the sample will give off heat.

Why is DSc used instead of differential thermal analysis?
Since DSC can measure directly both temperature and the enthalpy of a transition or the heat of a reaction, it is often substituted for differential thermal analysis as a means of determining these quantities except in certain high temperature applications.
