Laboratory X-ray source based high-energy-resolution spectrometers have been showing a renaissance that culminated in radical progression recently. Although techniques like X-ray Absorption Near Edge Structure (XANES), Extended X-ray Absorption Fine Structure (EXAFS) or X-ray Emission Spectroscopy (XES) were pioneered mainly on laboratory scale instruments, they have matured dramatically with the advent of synchrotron X-ray sources. The obvious excellence of these large scale photon sources in terms of X-ray brilliance, energy tunability, polarization, pulsed time structure, etc. over the conventional X-ray tubes turned the techniques mentioned dependent almost exclusively on occasionally accessible synchrotron beamtimes. However, the emergence of modern laboratory X-ray tube based spectrometers in the recent decade is being widely recognised, which give rise to a clear demand for such instruments.
