摘要
调制DSC(MIDSC)在常规的线性升温的基础上,叠加了正弦升温曲线,以缓慢的基础升温速率提高了分辨率,同时以快速的瞬时升温速率提高了灵敏度,将可逆和不可逆效应区分开来,在检测微弱转变、多相转交、测定初始结晶度、热容、热导率等方面显示出不可比拟的优势。
Modulated DSC (MDSC) is a technique which provides the same information as conventional DSC. However, a different heating profile is applied to the sample and reference. Specially, a sinusoidal modulation is overlaid on the traditional linear heating ramp. The slow underlying heating rate improves resolution and the faster instantaneous heating rate improves sensitivity. The total heating flow can be separated into reversing and nonreversing components. MDSC has many unique benefits to analyze the weak transitions, complex transitions, initial crystallinity, heat capacity and thermal conductivity .
