APPLICATIONS OF SYNCHROTRON-RADIATION-INDUCED X-RAY-EMISSION (SRIXE)

Synchrotron radiation-induced x-ray emission (SRIXE) is now a proven a nalytical method For the determination of trace elements, It is notabl e for spatial resolutions of less than 10 mu m and minimum detection l imits that can be as low as 1 ppm by weight, The approach to SRIXE mea surements in use at the Brookhaven National Synchrotron Eight Source i s summarized to illustrate the experimental approach to SRIXE. Applica tion of SRIXE to several different questions are then discussed. The p articular examples presented deal with the detection of trace amounts of (1) toxic metals in marine worms, tadpole brains and chick tibia an d (2) catalysts in polyolefin polymerization particles.
