Industrial Visit to CSIR: National Geophysical Research Institute

Event Description: The National Geophysical Research Institute (NGRI), a constituent research laboratory of the Council of Scientific and Industrial Research (CSIR) was established in 1961 with the mission to carry out research in multidisciplinary areas of the highly complex structure and processes of the Earth system and its extensively interlinked subsystems. One of the units of NGRI consist of ELECTRON PROBE MICRO ANALYSER (EPMA) CAMECA SX100 (EPMA).

EPMA works by bombarding a micro-volume of a sample with a focused electron beam (typical energy = 5-30 keV and size = 1-50 and collecting the X-ray photons thereby induced and emitted by the various elemental species. As the wavelengths of these X-rays are characteristic of the emitting species, the sample composition can be easily identified by recording EDS (Energy Dispersive Spectrometry) and WDS spectra (Wavelength Dispersive Spectroscopy). WDS spectrometers are based on the Bragg’s law and use various moveable, shaped monocrystals as monochromators. It has various applications in Earth and Planetary Sciences & Material Sciences.
