[交流] 纯度表征和DSC的Tzero技术

The determination of absolute purity by DSC has been an accepted technique since the mid 1960s. One source of error in the purity method, that has limited its applicability and accuracy, is uncorrected thermal lag. New DSC instrumentation incorporates these corrections directly into the heat flow signal. This superior approach leads to improved peak resolution and to more accurate purity analysis. It is likely that this advance will allow purity analysis to be performed at faster heating rates and the purity method will be extended to higher levels of purity.
