Trimethyloxonium tetrafluoroborate (TMO·BF4) has been used in the simultaneous derivatization of phosphonic and 2-aminoethylsulfonic acids related to nerve agents in different soils for their enhanced detection and identification by electron ionization gas chromatography-mass spectrometry (EI-GC-MS). The panel of acids consisted
