✦ Synopsis

Two methods that allow the determination of the boron content in a glass or a Ñux were compared. The Ðrst method uses direct measurement of B Ka Ñuorescence and subsequent fundamental parameter-based quantiÐcation. Although it can be used for low concentrations of B, it requires extra care with calibration because the fundamental parameters for boron depend on the chemical environment. The second method relies on the use of Comptonscattered radiation to determine boron as a light fraction in an otherwise known matrix. This method does not require matrix-dependent calibration, but it is insensitive for boron concentrations below about 4% of The B 2 O 3 . preferred approach is a combination of both methods.

X-rays scattered from a material contain information on the composition of the sample. The relationship between the sample composition and the amount of scattered radiation was studied for low-Z materials. Use of Comptonscattered tubelines appears to be the preferred technique and a calibration is p

The determination of trace elements in mineral water by preconcentration with ammonium pyrrolidinedithiocarbamate (APDC) is described. Samples were spiked with an internal Ga standard and the precipitated dithiocarbamates of trace elements were separated by Ðltration through a Nuclepore Ðlter. A sma
