Determination of light elements using x-ray spectrometry part II - Boron in glass

摘要

Two methods that allow the determination of the boron content in a glass or a flux were compared. The first method uses direct measurement of B K alpha fluorescence and subsequent fundamental parameter-based quantification. 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 Compton-scattered 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 B2O3. The preferred approach is a combination of both methods.
