| 中文简介: |  提供紧凑的模块化实验室装置，用于2 D SAXS，SWAXS和GISAXS，具有高亮度，有助于散装材料，液晶，（生物）聚合物或纳米颗粒溶液和薄固体薄膜的纳米结构分析。该系统S3 MICRO基于点聚焦微束传输系统（来自法国格勒诺布尔的Xenocs的GeniX）的组合，最大功率为50瓦，Hecus S3相机架构配有1 D和2 D探测器。利用单色化Cu辐射，可以容易地实现Qmin>0.003的SAXS分辨率，对应于~2000的d值。由于主光束的点横截面，不需要去除散射数据。光束亮度超过高功率旋转阳极SAXS系统的光束亮度> 3，而传统线聚焦系统的光束亮度超过两个数量级。这允许将纳米结构研究中的许多问题的测量时间减少到几秒，从而促进高通量（例如结构蛋白质组学）和在线过程分析应用。由于低功率（50瓦）和因此最小的冷却要求，系统设计非常紧凑和经济，因此最适合安装在多设施分析实验室或移动测试站。该软件包包括用于系统控制（基于SWAXView，Labview®）和在线数据分析（EASYSWAX）的模块，支持研发和质量控制中的自动多样品分析和常规分析应用。 |
| 课程简介: | A compact modular laboratory unit for 2-D SAXS, SWAXS and GISAXS with high brilliance is presented, that facilitates nanostructure analysis of bulk materials, liquid crystals, (bio-) polymer or nanoparticle solutions, and thin solid films. The system, S3-MICRO, is based upon a combination of a point-focus microbeam delivery system (GeniX from Xenocs, Grenoble, France) working at a maximum power of 50 Watt with the Hecus S3-camera architecture with 1-D and 2-D detectors. With monochromatized Cu radiation, a SAXS resolution of Qmin > 0.003 Å-1, corresponding to d-values of ~ 2000 Å, can be easily achieved. Due to the point-cross-section of the primary beam, desmearing of the scattering data is not required. The beam brilliance exceeds that of high-power rotating-anode SAXS systems by a factor of > 3, and that of conventional line-focussing systems by two orders of magnitude. This allows to reduce measuring times down to seconds for many problems in nanostructure research, facilitating high-throughput (e.g in structural proteomics) and on-line process analytical applications. Due to the low electrical power (50 Watt) and the consequently minimal cooling requirements, the system design is extremely compact and economical, and therefore optimally suited for installation in multi-facility analytical laboratories, or in mobile test stations. The software package includes modules for system control (SWAXView, Labview ® based) and for on-line data analysis (EASYSWAX) supporting automatic multi-sample analysis and routine analytical applications in R&D and QC. |
