PROCESS FOR THE DETERMINATION OF THE TOTAL BORON CONTENT AND THE COMBINED BORON CONCENTRATION OF A METAL SAMPLE.

摘要

The curve translating the variation in the light intensity of the radiation corresponding to the boron as a function of time is recorded, said curve having an initial peak and a substantially horizontal terminal plateau, the light intensity Ip corresponding to said substantially horizontal plateau is measured and the total boron content Bt of the sample begins therefrom; the light intensity It is also measured at at least an instant t corresponding to a point on said curve located between the top of the initial peak and the start of the substantially horizontal terminal plateau, and the concentration of combined boron BC of the is deduced therefrom sample.
