Fast atom bombardment and tandem mass spectrometry for characterizing fluoroalkanesulfonates

Identifying Hydrocarbon and Fluorocarbon Surfactants in Specialty Chemical Formulations of Environmental Interest by Fast Atom Bombardment/Mass Spectrometry

“…The m/z 499 was observed for a standard of perfluorooctane sulfonate (data not shown). No fragmentation corresponding to products with masses lower than the parent sulfonate anion were observed, which is consistent with the report by Lyon et al on fluoroalkyl sulfonates [5].…”

“…3). The ions corresponding to m/z 499 and 399 are characteristic of perfluorooctane sulfonate (C 8 F 18 SO 3 -) and perfluorohexane sulfonate (C 6 F 13 SO 3 -), respectively [5]. The m/z 499 was observed for a standard of perfluorooctane sulfonate (data not shown).…”

“…During the 1980s and early 1990s several reports on the use of FAB/MS for identifying surface-activeagents (surfactants) in commercial product [3][4][5][6] and environmental samples [7][8][9][10] appeared in the literature. The majority of reports describe the use of FAB/MS for the qualitative analysis of surfactants while only a limited number of reports describe the quantitative analysis of surfactants by FAB/MS [7][9] [11].…”

Simultaneous qualitative and quantitative analysis of fluoroalkyl sulfonates in riverine water by liquid chromatography coupled with Orbitrap high resolution mass spectrometry

“…2 [32], the observed cleavage patterns involving a remote charge fragmentation mechanism to generate a series of [C n F 2n SO 3 ] − anions as well as homolytic unzipping [C n F 2n + 1 ] − ions due to fluorine migration effect after initial loss of SO 3 were thoroughly investigated in previous studies [33]. Obvious differences were also found between HCD and CID fragmentation, which could be influenced by many factors.…”

Charge‐remote fragmentations: Analytical applications and fundamental studies

“…Both positiveand negative-ion MS-MS have been used to determine anionic surfactants. The positive-ion CID spectra of (M + H)+ and (M + Na)+ ions of sodium alkyl-and alkylbenzenesulfonates have been acquired by using FD-MS-MS (5,6), whereas the negative ion CID spectra of alkyl-and alkylarylsulfonates, perfluoroalkanesulfonates, alkylether sulfates, N-acylated amino acids, and sulfopolycarboxylates have been evaluated by using FAB-MS-MS (47,48).…”
