“…Mass spectrometry coupled with desorption ionization techniques has become a powerful tool for surfactant analysis in environmental sample matrices (14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24). LAS analysis by field desorption mass spectrometry (FD/MS) and MS/MS was first demonstrated in 1982 (14,15). Subsequently, FD/MS and MS/MS have been applied to identifying LAS in river water (17), sewage (19), and surface water (21).…”

“…To the best of our knowledge, the first observation of surfactant aggregates in the gas phase using a mass spectrometric technique was reported by Weber et al in 1982. 16 By means of field desorption (FD) and collisional-activated dissociation (CAD), some mixtures of cationic, anionic and non-ionic surfactants were analyzed. Even if the main aim of the work was to gain a straightforward and unequivocal structure elucidation of these compounds, the appearance of some charged surfactant aggregates with n < 6 both for cationic and anionic surfactants was also reported.…”

In contrast with the enormous amount of literature produced during many decades in the field of surfactant aggregation in liquid, liquid crystalline and solid phases, only a few investigations concerning surfactant self- assembling in the gas phase as charged aggregates have been carried out until now. This lack of interest is disappointing in view of the remarkable theoretical and practical importance of the inherent knowledge. The absence of surfactant-solvent interactions makes it easier to study the role of surfactant-surfactant forces in determining their peculiar self-assembling features as well as the ability of these assemblies to incorporate selected solubilizate molecules. Thus, the study of gas-phase surfactant and surfactant-solubilizate aggregates is a research subject which has exciting potential, including mass and energy transport in the atmosphere, origin of life and simulation of supramolecular aggregation in interstellar space. On the other hand, the structural and dynamic properties of surfactant aggregates in the gas phase could be exploited in a number of interesting applications such as atmospheric cleaning agents, transport and protection of pulmonary drugs or biomolecules and as nanoreactors for specialized chemical reactions in confined space. Spectrometric techniques, together with molecular dynamics simulations, have been the principal investigative tools in this field and appearto be particularly suited to gaining fundamental information on the structure and stability of surfactant-based supramolecular aggregates, charge state effects, entrapment of solubilizate molecules, preferential solubilization sites and chemical reactions localized in a single organized aggregate. The main aim of this review is to present the actual state of the art in this novel and exciting research field underlining the knowledge acquired up to now as well as the aspects needing a more deep understanding. Moreover, intriguing departures of the behavior of surfactant solutions under electrospray ionization conditions from that of ionic, polar and apolar analytes will be discussed.

“…Several reports have included some description of polyglycol tandem mass spectrometry behavior. Ionization methods employed include field desorption [1][2][3], chemical ionization , and fast atom bombardment [7][8][9][10][11]. Many of these studies reported sequential losses of ethylene oxide (EO) units from the precursor ions.…”

A study of the fast-atom bombardment tandem mass spectrometry behavior of a number of ethylene glycol polymers (PEGs) has been carried out. Both linear (hydroxyl, amino, and/or alkyl end groups) and cyclic (crown ether) polymers were studied. One of the materials is a block copolymer of ethylene and propylene oxides. Collisional activation was carried out in the collision octapole of a BEoQ hybrid mass spectrometer at a translational energy of 50 eV, with collision gas air. For the linear polymers, the most intense product ions are lithiated, linear polyglycol oligomers, These ions are formed via internal hydrogen transfer reactions that are facilitated (charge-induced) by lithium. This series of product ions allows for the observation of consecutive losses of monomer units from the chain end; this is useful to determine the sequence of monomers in a copolymer. The most abundant product ions from cyclic PEGs are lithiated radical cations. An especially interesting finding in this work is the preferential loss of two internal ethylene oxide (EO) units (dioxane, 88 u) from some [M + Li](+) precursors. Factors that influence this loss include (a) the sequence length of EO repeat units in the oligomer and (b) the identity of the end groupts) on the oligomer. It is proposed that this elimination of dioxane involves a six-membered ring intermediate; this decomposition reaction is believed to be a lithium-mediated (charge-induced) rearrangement.
