A method for identification of some alkyl methylphosphonic acids in aqueous samples by liquid chromatography coupled to thermospray tandem mass spectrometry is described. The compounds are separated by reversed‐phase liquid chromatography and identified by their daughter spectra after collision‐induced dissociation of the quasi‐molecular ions produced by the thermospray interface. The combination of liquid chromatographic separation of the acids with detection of the compoounds by tandem mass spectrometry gives enough information to identify the compounds. A twenty‐to‐fifty‐times improvement in the signal‐to‐noise ratios, compared to normal thermospray detection, has been observed in these experiments.
