网络研讨会: From sample preparation to X-ray fluorescence analysis

This webinar provides a comprehensive overview of the analysis-neutral and reproducible preparation of different solid samples and the subsequent analysis. It is addressed to all users who would like to optimize the sample preparation and analysis in the laboratory qualitatively and quantitatively.

Several online demos of selected devices and time for answering participants' questions round off each webinar block.

RETSCH: The Art of Milling

The online seminar focuses on the importance of sample preparation for subsequent analysis and describes ways of eliminating potential sources of error. You will receive useful tips for choosing the optimum crusher or grinder and the best suited accessories. The importance of correct parameter setting will also be explained.

Topics

  • Why is sample homogenization necessary and what needs to be considered for the process?
  • How do different size reduction principles work for different samples?
  • Live demonstration of RETSCH crushers and mills in the application lab, from pre-grinding to pulverization

元素分析--RFA 的有益补充

现代燃烧分析主要包括 "轻 "元素(C、H、N、O 和 S),XRF 只能对其进行有限的定量测定。网络研讨会通过选定的示例展示了元素分析仪的典型应用。

主题

  • 如何使用 XRF 分析燃烧?
    • 元素分析是如何运作的?
    • 燃烧分析与 RFA 的对比
    • 应用示例

SPECTRO: XRF 测量原理和标准

本网络研讨会简要介绍了 XRF 分析的功能和可能性,以及如何分析粉末样品和压片。通过一些实际案例,我们展示了在更好地制备和分析样品方面存在的问题和可能的解决方案。大量德国和国际标准都将 XRF 描述为一种分析方法。本讲座旨在概述一些标准,并提示这些标准对分析方法实际使用的重要性。

主题

  • 什么影响 XRF?
    • 例如,样品成分、粒度、均匀性和基质对分析结果有什么影响?
    • 有哪些标准?
    • 实验室日常工作的实用技巧
