Sediment cores contain valuable information on geological history and palaeoclimate, and it is necessary to study cores at high spatial resolution to recover useful palaeoenvironmental data. This paper describes an innovative micro-X-ray fluorescence spectrometer that can measure spot sizes in the range of 50 μm, with incremental step sizes down to 10 μm. The analysis is non-destructive so the sediment core is preserved and available for other investigations. This paper describes the new instrument, the Eagle III BKA system, which employs some novel features such as a polycapillary lens, moveable sample stage and X-ray head, a Varispot focusing system and an environmental sample cabinet. Some examples of recent applications are described.
