Elemental mapping is an imaging technique used to visualize the spatial distribution of elements within a material. X-ray fluorescence (XRF) spectrometry is a widely used analytical technique for this purpose due to its ability to provide information on a broad range of elements, making it an ideal tool for studying compositional zonation and determining the elemental composition of a material.

Analysis: It s 150 years since Dmitri Mendeleev came up with the Periodic Table of chemical elements and transformed chemistry
What s all the fuss about?
Dmitri Mendeleev s discovery in St Petersburg in 1869 was a landmark event that was to transform chemistry from a tangle of disorganised facts into a disciplined science. It was to formulate the thinking of generations of scientists to come and to be a feature of every future chemistry textbook from Junior Cycle to undergraduate. His table would arrange 63 elements, (an element is a substance that is made up of identical atoms), into a recognisable and repeating pattern that all the other 58+ elements, yet to be discovered, would follow.
