拉曼光谱无损鉴别实验

检测项目

化学成分定性分析：通过比对样品拉曼光谱与标准谱图库，确定物质的主要化学成分及官能团信息。

晶体结构鉴别：依据拉曼光谱中特征峰的位移和强度变化，判断材料的晶型、晶相以及是否存在多晶型现象。

聚合物材料表征：分析高分子链的构象、立体规整度以及共聚物序列分布，评估聚合物的化学结构。

药物多晶型筛查：检测药物活性成分的不同晶型，监控生产过程中可能出现的晶型转变或混晶情况。

碳材料缺陷分析：通过D峰与G峰的强度比及峰形特征，定量评估石墨烯、碳纳米管等材料的缺陷密度和有序度。

表面增强拉曼散射检测：利用纳米结构金属基底增强信号，实现对痕量吸附分子或生物大分子的高灵敏度检测。

应力应变分析：测量材料在受力状态下拉曼特征峰的位移，推算其内部应力分布和弹性模量参数。

生物组织病理诊断：基于生物大分子的特征光谱差异，区分正常组织与病变组织的生化组成变化。
