Bondar Clegg, energy-dispersive XRF

Bondar Clegg barium analysis by energy-dispersive X-ray fluorescence.  Detection limit = 20 ppm.

General Methodology:

Barium is determined using energy-dispersive X-ray fluoresecence according to the method described by Bright (1983).  A 5 gm sample is placed in a 10 ml plastic vial.  The sample is exposed to a radioactive source and the intensities of X-rays emitted are measured.  The amount of barium is measured by comparison to standards.  Corrections are made for inter-element interferences.
