X-Ray Fluorescence (XRF) spectrometry for materials analysis and discovering "the atomic number"
written by
Asma Khalid, Aleena Tasneem Khan, and Muhammad Sabieh Anwar
published by the LUMS School of Science and Engineering
In this experiment students use XRF spectroscopy to analyze a sample's elemental composition. From the characteristic X-ray energies, Moseley's Law, a proof of the existence of the atomic number, is verified. The atomic number increases in regular steps with an increase in the characteristic X-ray energy. We will use this relationship to find the Rydberg's energy constant and screening coefficient for K X-rays.
This lab is designed for the student to learn to: 1. differentiate between characteristic X-rays and Bremsstrahlung radiations, 2. use characteristic X-rays to identify elements, 3. acquire a spectrum, calibrate it and use it for qualitative (element identification) as well as quantitative (elemental concentration) analysis, and finally, 4. verify Moseley's law and the validity of an atomic number.
