3 X-ray Fluorescence Spectrometry

3.1 Principle

Put the prepared sample in sample chamber of x-ray fluorescence spectrometer and analyze the sample according to selected test mode. Then judge whether the content of bromine element in the sample is qualified according to the screening limits for respective sample and whether accurate determination is needed.

3.2 Reagents and materials

3.2.1 Boric acid (HBO3): analytically pure, heated at 105℃ for 1h and stored in a dryer.

3.2.2 Bromine-contained standard material.

3.2.3 Liquid nitrogen: industrial-grade.
