WebA commercial ion microprobe mass analyzer (IMMA) has been interfaced with a tunable pulsed dye laser for carrying out resonance ionization mass spectrometry of sputtered atoms. The IMMA instrument has many advantages for this work, including a micro-focused primary ion beam ... Web19 jul. 2024 · In this study, we obtained in situ major element compositions (by using Electron microprobe analysis—EMPA) and trace element compositions (by using laser ablation inductively coupled plasma mass spectrometry— LA-ICP-MS) for minerals (clinopyroxenes (Cpx), plagioclases (Pl), and olivines (Ol)) hosted by late Cenozoic … WebTherefore the ion microprobe instruments were improved through time to reach mass resolving power (MRP = M/∆M) from a few hundreds up to more than 30,000. The aim of this talk is first to retrace the evolution of Ion microprobe instruments toward high MRP over these sixty years, using different technical choices based on the physics of secondary … gregg county tax appraisal
