The problem is compounded by the formation of hydrates of the characteristic primary product ions of the reactions of the H3O+ and NO+ precursor ions with these compounds, this being particularly efficient for humid samples such as exhaled breath. Thus, the resulting product ion spectra are complex and choices have to be made as to which of the characteristic product ions and their hydrates can best be used for the quantitative analyses.
