高分子聚合物

了解聚合物的特性是优化其性能的关键步骤。雷尼绍拉曼系统为您提供研究聚合物所有种类的能力和灵活性。

分析所有的聚合物

高分子聚合物的种类成千上万,其中许多已得到非常广泛的应用。使用SynchroScan(同步连续扫描)光谱采集和数据库搜索功能,尽可能增大识别聚合物的机会。SynchroScan以高光谱分辨率为您呈现拉曼谱带。这使得进入雷尼绍聚合物数据库中搜索变得简单而可靠。

拉曼光谱使您能够:

  • 描绘叠层薄膜,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

可以使用拉曼散射,确定透明的聚合物叠层的组分和厚度。要成功进行分析,您需要一台具有较好的深度分辨率和在三维空间准确定位样品的系统。inVia共焦显微拉曼光谱仪,连同其EasyConfocal(轻松共焦)技术,以及HSES样品平台是进行此分析的理想工具。

利用LiveTrack™研究物理变化

LiveTrack实时聚焦追踪技术有助于在样品出现膨胀、收缩或相变时,实时保持最佳聚焦,从而便于研究样品的动态物理变化。

    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.

    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.
