Selected ion flow tube mass spectrometry, SIFT-MS, can be used to determine the absolute humidity of air, breath and liquid headspace samples. This involves the determination of the relative count rates of the H3O+ ions and those H3O+. (H2O)1,2,3 hydrate ions that form in the helium carrier gas when humid samples are being analysed by SIFT-MS using H3O+ precursor ions.
