Presentation Title: High Purity Lanthanum and Yttrium-Based Materials Analysis by Astrum ES Glow Discharge Mass Spectrometry
Abstract: High purity lanthanum and yttrium-based materials are important materials and additives to emerging and high-tech industries, including solar energy, optoelectronics, lithium batteries, and biomedicine. Direct analysis of these materials by glow discharge mass spectrometry (GDMS) provides consistent,
reproducible, low detection limits, while avoiding the complexities and contamination introduced by wet chemistry.
The Astrum ES is a forward-geometry magnetic sector instrument. It utilizes a cryo-cooled low pressure direct current GD source. It has 2 detectors – an ion counter and Faraday detector. The Astrum has been designed to replace the industry standard VG9000. The newer optics in the Astrum ES also translate to better abundant sensitivity relative to the VG9000 while maintaining comparable ion transmission yields and sensitivity.
Analysis of nonconductive oxide materials pose a challenge to analysis by GDMS. Since the sample acts as the cathode, it is required to be conductive. The solution to that is the utilization of conductive holding electrodes. The holding electrode is often composed of high purity tantalum. It supports the plasma and assists with the sputtering of the material being analyzed. It is imperative to ensure that this difference in sputtering mechanism and bond strength (as compared to conductive metals) provides repeatable and reproducible data.
In this study we analysed high purity lanthanum and yttrium-based reference samples across multiple days and analysts on the Astrum ES. Utilizing certified and consensus values, we are able to monitor multiple different impurities present in these materials and calculate the statistics to demonstrate the Astrum ES repeatability and reproducibility analyzing these materials.
