Hace 2 días · 1 Introduction. Since chemist Robert Bunsen and physicist Gustav Kirchhoff established the first instrumental analysis based on flame emission spectroscopy, spectrometry has played an important role in analyzing atoms and molecules ( Casasanta, 2023; Davidson, 2011; Hennig, 2022 ).
Hace 1 día · Rubidium was first discovered by the German chemists Robert Bunsen and Gustav Kirchhoff in 1861 through spectroscopic analysis of mineral samples. It is a relatively rare element in the Earth’s crust, occurring in trace amounts in minerals such as lepidolite, pollucite, and carnallite.
Hace 5 días · Kirchhoff's ground-breaking research was extraordinarily diverse, spanning electrical, magnetic, optical, elastic, hydrodynamic and thermal processes. His laws for electrical circuits are well-known. At the time he was in Heidelberg, in conjunction with Robert Wilhelm Bunsen, he discovered spectral analysis and its application to ...
