Application of 7N In as secondary cathode for the direct current-glow discharge mass spectrometry analysis of solid, fused high-purity quartz
Direct current glow discharge mass spectrometry with an indium-based secondary cathode technique is used to analyze solid, nonconducting, fused high-purity quartz regarding metallic impurities of relevance to the solar industry. Details of the analytical routines are presented. In this work, the secondary cathode design and glow discharge conditions are optimized beyond the commonly applied practices. In addition, relative sensitivity factors (RSFs) for these optimized conditions are established and compared to previously published results. The results indicate that the technique enables stable measurements with detection limits down to the part per billion (ppb) range.publishedVersio
Structural Characterization of Natural Quartz by Scanning TEM
For quartz, despite its industrial importance and an extensive amount of research done on it, there are still open fundamental questions, e.g. regarding crystal defects, phase changes or damage mechanisms under ionizing radiation [1,2]. Transmission electron microscopy (TEM), widely deployed to investigate crystal structures down to Å level, has scarcely been published with respect to quartz in the last decades. The reason for this, beside challenges in preparing good specimens, is that this mineral is very beam sensitive and rapidly becomes amorphous during TEM investigations.acceptedVersio
