主题：【分享】PE推出DSC——拉曼系统

2009 年，PerkinElmer , Inc. 推出其独有的差示扫描量热法(DSC)——拉曼光谱法联用系统。

DSC-拉曼系统配备了双炉DSC 8500 和RamanStation (TM) 400 光谱仪。该方法首先使用拉曼光谱仪同步分析化学和结构信息,然后将这些信息与DSC 生成的量热数据相关联。几家大型制药公司和大学对联用技术进行了测试,发现这些技术能够更加深入地分析聚合体结晶、药物载体的相互作用、硫化和多晶改变。这些创新能够减少客户的研发时间,将性能和疗效更佳的新材料和药物更快速地推向市场。

DSC-Raman Hyphenation

DSC and Raman spectroscopy are two complimentary techniques that when combined provide greater insight into material changes of polymers and pharmaceuticals at a molecular level. The structural information gained from Raman spectroscopy is precisely correlated with energy changes in the DSC. This allows you to gain a greater understanding of what happens to a sample at various temperatures, changes previously unseen by a single technique.

PerkinElmer’s double-furnace DSC design immediately compensates for the energy from the Raman laser allotting for minimal temperature change in the sample being analyzed so the heat from the laser does not push the sample through a transition, which would give inaccurate results.
