An experimentally determined mass of an [[ion]] that is used to determine an elemental formula. For ions containing combinations of the elements C, H, N, O, P, S, and the halogens, with mass less than 200 [[u]], a measurement with 5 ppm uncertainty is sufficient to uniquely determine the elemental composition. | |||
