Quantitative Analysis (cont.)Sx=( A+ B)AIIxAg(pure)Where I xis the amplitude of the known compound, (A+B)/A is the 1 /fraction of X atoms and I x/ I Agthe ratio of peak to peak amplitudes.THEN from an unknown sample: C x= I x/ I Ag. S x= concentrationOR to make it self consistent C x=(I x/S x)/∑ a (I a/S a)where I xand I aare measured and S xand S aas mentioned aboveare obtained from standards
