With a 7-[micro]m-diameter beam, Sr was measured by using the TAP crystal (Sr L[alpha]) and Ca was measured by using the PET crystal (Ca K[alpha]).
The mean Ca was 197,400 ppm when Sr was measured on the PET crystal and 202,100 ppm when Sr was measured on the TAP crystal.
Using the TAP crystal to measure Sr, we found that the minimum limit of determination for Sr was 103 ppm and 65 ppm in the high Sr/Ca and low Sr/Ca regions, respectively.
