Abstract: An X-ray microprobe for trace elemental analysis at micrometer spatial resolutions, using synchrotron radiation (SR), is under development. The facility consists of two beamlines, one including a 1:1 focusing mirror and the other an 8:1 ellipsoidal mirror. At present, “white light” is used for excitation of the characteristic X-ray fluorescence lines. Sensitivities in thin biological samples are in the range of 2–20 fg in 100μm 2 areas in 5 min irradiation times. Scanning techniques, as well as microtomography and chemical speciation, are discussed. Application to a specific biomedical study is included.
