聚合物和塑料微粒
了解聚合物的特性是优化其性能的关键步骤。雷尼绍的拉曼系统具有研究所有种类聚合物的能力和灵活性。
分析所有聚合物
使用SynchroScan（同步连续扫描）光谱采集和数据库搜索功能，可大幅增加识别数千种聚合物的可能性。SynchroScan以高光谱分辨率为您呈现拉曼谱带。因此，您在雷尼绍聚合物光谱数据库中轻松且可靠地进行搜索。
拉曼光谱能够：
- 表征叠层薄膜，无需对其进行机械切片
- 研究聚合物混合物
- 分析纤维的应力
- 确定结晶度水平
- 研究用于封装光伏电池的材料
- 研究新型聚合物，例如导电聚合物
精确地确定层厚
通过拉曼散射可确定透明聚合物叠层的成分和厚度。为实现成功分析，您需要一台具有较好的深度分辨率，并且可在三维空间精确定位样品的系统。inVia共焦显微拉曼光谱仪，搭载EasyConfocal（轻松共焦）技术以及高速光栅尺反馈平台 (HSES)，是进行此类分析的理想工具。
利用LiveTrack™研究物理变化
LiveTrack实时聚焦追踪技术可在样品出现膨胀、收缩或相变时实时保持聚焦，从而便于研究样品的动态物理变化。
可重复的光谱
聚合物的某些参数（如结晶度）的变化会导致拉曼光谱产生相对细微的变化。雷尼绍的inVia显微拉曼光谱仪具有高光谱分辨率、精度和稳定性，可帮助您观察这些变化。

Application note: Analysing microplastics with the inVia™ confocal Raman microscope [en]
Plastics are extensively used in products and packaging and, unfortunately, make their way into the environment, causing significant issues for wildlife. In addition to concerns about bulk plastic contamination, there has been much interest in microplastics. Raman spectroscopy, an optical scattering technique, has much to offer researchers investigating plastics, as it can identify them rapidly and non-destructively.

Application note: Study polymers with the inVia confocal Raman microscope [en]
The Renishaw inVia confocal Raman microscope is ideal for the 2D and 3D chemical analysis of polymers. Synthetic polymers display a broad range of properties and are extensively used in modern products. The study of polymers in terms of identification, spatial distribution and concentration is important as we search for novel materials, improve effectiveness of existing materials, and reduce the costs of products. The inVia microscope provides chemical specificity and sensitivity, in a non-destructive manner, with no sample manipulation and preparation required.
