Our N8 HORIZON Small and Wide Angle X-Ray Scattering (SAXS - WAXS) system was developed in accordance with the principles of our DAVINCI design: Take the best analytical method and most advanced technologies and combine them with ultimate ease-of-use and safety to offer a perfect solution for all applications. Mirror-conditioned circular pinhole collimation, a versatile, ergonomic sample chamber and a large 2-D detector are the key components that put you in the best starting position for successfully tackling any type of SAXS experiment. Our latest developments in optics technology allowed us to significantly shorten the traditionally long primary beam path and paved the way for our unique vertical instrument design with horizontal sample mounting.

主要特征

N8 HORIZON Features

Patented vertical beampath

The most prominent characteristic of our N8 HORIZON – compared to traditional SAXS systems – is the innovative vertical instrument setup. This simple rotation offers two major benefits: Firstly, no other system with comparable performance
在有价值的实验室空间中具有如此小的占地面积。其次,重力为您工作。样品很容易水平安装,不需要固定辅助工具。在测量过程中,样品永远不会流出,下沉或掉落X射线梁。

N8 HORIZON Features

IµS微焦点源

这种独特的X射线源可提供非常稳定和强烈的斑点X射线梁,而无需进行水冷却。得益于其强大的设计,该消息来源具有3年的保修。IµS包括集成的MONTEL,最先进的2-D光束成型光学元件,以最高强度。这种并排的多层镜设计可从源捕获大的X射线固体角度,并在高度平行和单色梁中有效地重定向。

N8 HORIZON Features

VÅNTEC-500 2D detector

带有Mikrogap的Våntec-500 2-D检测器TM技术满足专用SAXS系统的所有理想要求。首先,不需要气体,水或常规维护,也不需要对强烈的辐射或运动损伤的疑虑导致探测器强大且易于使用。一个大的活动区域(14 x 14厘米2),以全面的视野使巨大的角度覆盖范围。令人难以置信的低背景和高最大计数率,对于奇妙的动态范围和对弱散射样品的敏感性。出色的空间分辨率来解决紧密间隔的散射特征。没有其他探测器可以为这些应用提供这些理想功能的组合。

Key Applications

N8地平线应用

小角度X射线散射(SAXS)

小角度X射线散射(SAXS)是由嵌入不同电子密度基质中的颗粒引起的现象。如果粒径范围从1 nm到200 nm,则散射角位于0°至5°的范围内,具体取决于所使用的X射线波长。颗粒越小,较宽的是散射角。

Any arrangement of particles in any medium shows a difference in electron density, which results in a specific pattern when executing a SAXS experiment. Along with the size of the particles, SAXS can also determine their shape, their distance apart and size distribution from the 2-D pattern. Particles can be dissolved macromolecules, precipitations in metals, mineral particles in biological tissues, and surfactant micelles.

N8地平线应用

Grazing-Incidence SAXS (GI-SAXS)

为了探测表面和地下结构细节,样品以放牧的入射率几何形状进行测量。入射角接近所谓的总反射的临界角,通常位于0.1至0.7度之间。在放牧的小角度X射线散射(GISAXS)实验中,通过二维检测器通过二-D检测器在非旋转方向上收集扩散的散射强度。

A dedicated GI-SAXS stage with motorized tilt is used to align the sample in the beam.

N8地平线应用

Wide-Angle X-Ray Scattering (WAXS)

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nd检测器位置更接近样品。
