  • Introducing APEX 3.0 Software – now with EDS, EBSD, and WDS
    Introducing APEX 3.0 Software – now with EDS, EBSD, and WDS

    Thursday, March 23, 2023

    The new APEX 3.0 software is the ultimate materials characterization software suite integrating energy dispersive spectroscopy (EDS), electron backscatter diffraction (EBSD), and wavelength dispersive spectrometry (WDS) to deliver previously unattainable solutions. This optimized configuration offers the uncompromised performance of each technique and allows users to combine them for the ultimate materials insight. All three techniques seamlessly operate within APEX, blending powerful elemental and crystallographic analysis routines through an intuitive interface delivering outstanding data collection, faster analysis, and flexible reporting for users of all levels. In this webinar, WDS capabilities, the latest addition to this software suite, will be introduced, and application examples will be presented.

    「OIM - 新時代」OIM-A9 の新機能のご紹介

    Wednesday, February 22, 2023

    EDAX/TSLでは、今春OIM-A9をリリースする予定です。OIMではOIM-A8から解析ソフト上で保存されたEBSDパターンの再指数付けができるようになっています。従来のHough変換に基づいた指数付けは、高速に動作させることができ、非常に有用な手法です。しかし、この手法は不鮮明なパターンに対しては、精度の高い指数付けは困難となってしまいます。この問題を解決するために、シミュレーションパターンに基づいたDictionary Index法をOIM-A8.6で導入しました。しかし、計算が非常に重くあまり実用的ではありませんでした。OIM-A9では同じシミュレーションパターンに基づいた指数付けですが、パターンの参照方法を改善し、従来のHough変換法に基づいた遜色のない速度で指数付けが可能なSpherical Index法を開発し組み込むことに成功しました。本セミナーでは、このSpherical Index法を中心にOIM-A9の機能を紹介します。

  • EDX Quantifizierung mit Standards als alltagstaugliches Verfahren durch FSQ in APEX
    Establishing EDS Quantification with Standards as a Technique for Everyday Use with FSQ in APEX

    Thursday, February 16, 2023

    With the latest APEX software, EDAX enables extensive flexibility in quantifying energy dispersive spectroscopy (EDS) analyses. While the eZAF model considers matrix effects, PeBaZAF is useful for geometrically demanding materials that use the peak-to-background ratio instead.

    Standardless normalized quantification is the most widely used approach due to its ease of use, fast and ready-to-use results, and it utilizes minimal requirements to perform this analysis. Since the equation system is underdefined, normalizing the element weight fractions is necessary.

    During this webinar, we demonstrate how APEX introduces the so-called reference. It uses a short measurement of a single-element standard to determine a unique scaling value to eliminate the unknown physical parameters allowing non-normalized results.

    When measuring a standard, the associated reference value is impinged to the spectrum and can thus account for differences with respect to the sample measurement. This significantly reduces the complexity of the quantification procedure and enables the creation and use of a database. An implemented algorithm is available for standard selection.
