拉曼光谱必备试剂，精准解锁物质微观 “密码”-百灵威

拉曼光谱是分析纳米颗粒的关键手段。原理是单色光照纳米颗粒产生拉曼散射光，其频率位移反映颗粒结构信息。用拉曼光谱仪将纳米颗粒制成合适样品测光谱，能鉴定结构、分析成分、探究表面性质、监测应力应变。它有非侵入、分辨率高优势，也有散射光弱、易受荧光干扰缺点，联用技术可拓展应用。

百灵威可提供多种用于窄谱带的OLED发光材料，详细产品信息如下：

1、拉曼光谱增强试剂

增强试剂的作用在于显著提高检测灵敏度，让低浓度样品的微弱拉曼信号得以检测；拓宽检测范围，使拉曼活性低的分子信号可被检测；甚至在理想条件下能实现单分子检测，为研究分子行为提供有力工具。
