Imaging and imaging techniques are a constantly growing area of major interest in science. This great success is certainly due to the fact that we humans perceive information much better when it is visualized. In fact, images allow us to absorb large amounts of data quickly. In science, visual observation has always been an important way for acquiring new knowledge and then communicating it with the help of images. In the past the development of microscopes was an important milestone in gaining structural insights into the microworld. Nowadays, there is great interest in combining structural information with chemical information: How can we obtain knowledge on the presence and quantity of chemical elements in each pixel of an image? To answer this question, many different atomic spectrometry techniques are available today to chemically map the surfaces of samples in the micro to nanometer range. This lecture will highlight important analytical tools for elemental imaging including laser ablation ICP-MS, secondary ion mass spectrometry (SIMS), laser induced breakdown spectroscopy (LIBS), and synchrotron-based X-ray absorption spectroscopy. The general concept of these techniques has in common that the sample surface is scanned by a beam (photons, electrons, or ions) and the resulting element-specific signals (spectra or ions) are recorded. The application fields are numerous ranging from biology and medicine to geology and material sciences, which will be illustrated by examples from current research. Limitations and new challenges will also be discussed, along with future developments towards two- and three-dimensional multimodal, multiscale and correlative imaging.
