Quantitative EPMA for the ultralight elements boron through oxygen

The practical problems in quant. electron probe microanal. of the ultra-light elements B, C, N, and O are discussed and solns. to these problems are given. It is shown that the basic requirement for accurate intensity measurements is the integral recording of the light element emission peaks in order to deal with the strong alterations in the peak shapes that sometimes occur. It is demonstrated that when these effects are properly accounted for and a good matrix correction program in conjunction with consistent mass absorption coeffs. is used good quant. results can be obtained.
