Most interesting materials in nature are heterogeneous, so it is useful to have analytical techniques with spatial resolution sufficient to resolve these heterogeneities. This article presents the basics of X-ray photon-in/photon-out chemical imaging. This family of methods allows one to derive images reflecting the chemical state of a given element in a complex sample, at micron or deep sub-micron scale. X-ray chemical imaging is relatively non-destructive and element-selective, and requires minimal sample preparation. The article presents the basic concepts and some considerations of data taking and data analysis, along with some examples.
