A 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 100 ..mu..m/sup 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. 13 refs., 2 figs.
