N8地平线

我们的N8地平线小和广角X射线散射（SAXS-WAXS）系统是根据我们的Davinci设计的原理开发的：采用最佳的分析方法和最先进的技术，并将它们与最终的易用性和安全性结合在一起为所有应用提供完美的解决方案。镜面条件的圆形针孔准直，多功能，人体工程学样品室和大型二维检测器是使您处于成功处理任何类型的SAXS实验的最佳起始位置的关键组件。我们在光学技术方面的最新发展使我们能够显着缩短传统上长的主要光束路径，并为我们独特的垂直仪器设计铺平了道路，并具有水平样品安装。

与传统的SAXS系统相比，我们N8 Horizo​​n最突出的特征是创新的垂直仪器设置。这种简单的轮换提供了两个主要好处：首先，没有其他具有可比性能的系统
has such a small footprint in valuable lab space. Secondly, gravity is working for you. Samples are easily mounted horizontally with no need for fixing aids. During measurement, samples will never flow, sink or fall out of the X-ray beam.

The VÅNTEC-500 2-D detector with Mikrogap^TM值technology satisfies all of the ideal requirements of a dedicated SAXS system. First, no need for gas, water, or routine maintenance and no concerns for intense radiation or movement damage results in detector that is robust and very easy to use. A large active area (14 x 14 cm²) to enable huge angular coverage with full field of view. Incredibly low background and high maximum count rate for fantastic dynamic range and sensitivity to weakly scattering samples. Excellent spatial resolution to resolve closely spaced scattering features. No other detector can offer these combination of ideal features for these applications.

Small Angle X-ray Scattering (SAXS) is a phenomenon caused by particles embedded in a matrix of different electron density. If the particle size ranges from 1 nm to 200 nm, the scattering angle lies within the range of 0° to 5°, depending on the X-ray wavelength used. The smaller the particles are, the wider are the scattering angles.

在任何介质中的任何排列都显示出电子密度的差异，这在执行SAXS实验时会导致特定模式。除了颗粒的尺寸外，萨克斯州还可以确定它们的形状，分开的距离以及与2-D模式的尺寸分布。颗粒可以溶解大分子，金属中的降水量，生物组织中的矿物颗粒和表面活性剂胶束。

与SAX相比，广角X射线散射（蜡）检查了埃埃斯特罗姆水平的结构，这些结构通常是晶体结构的间距离。通常，蜡用于分析Bragg X射线衍射（XRD）图案，该图案可以帮助确定晶体结构，结晶度，结晶石大小和相组成（相位ID）。蜡数据通常是（同时）作为带有2的萨克斯数据的同时收集的^nddetector positioned much closer to the sample.
