Depth profiling at a steel-aluminum interface using slow-flow direct current glow discharge mass spectrometry
Paudel, Gagan; Langelandsvik, Geir; Khromov, Sergey; Arbo, Siri Marthe; Westermann, Ida; Roven, Hans Jørgen; Di Sabatino Lundberg, Marisa (Journal article; Peer reviewed, 2021) -
Exploring glow discharge mass spectrometry applications in materials characterization
Paudel, Gagan (Doctoral theses at NTNU;2021:232, Doctoral thesis, 2021)Glow discharge mass spectrometry (GDMS) relying on continuous direct current discharge source coupled to sector field mass analyzer (SF-GDMS) is popular for its ability to detect impurities in sub-ppb level. Astrum GDMS ... -
Influence of polycrystalline material on crater shape optimization and roughness using low power/low-pressure direct-current glow discharge mass spectrometry
Paudel, Gagan; Khromov, Sergey; Kasik, Martin; Roven, Hans Jørgen; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2020)Depth profiling is an attractive approach for analysis of non-homogeneous samples and layered materials. This application requires an optimum sputtered crater profile, which means a flat crater bottom with steep walls and ... -
Silicon and indium as secondary cathodes for the analysis of solid alumina and sapphire by slow-flow direct-current glow discharge mass spectrometry
Busam, Jochen; Paudel, Gagan; Di Sabatino Lundberg, Marisa (Peer reviewed; Journal article, 2022)We demonstrate and compare the capabilities of indium and silicon as secondary cathodes for the analysis of flat, solid alumina and sapphire matrices by direct current glow discharge mass spectrometry (dc-GDMS). The mask ...
