“…Tandem mass spectrometry on the ion at m/z 214 gave fragment ions at m/z 158, 141, 77, 57, 55, 43, and 41 all of which were also observed at comparable intensities in the MS/MS spectrum of a sample of N-butylbenzenesulfonamide, synthesized in the regular manner from benzenesulfonyl chloride and 1-butanamine. The origin of this compound is not clear, although it is used as a plasticizer for polyamides [28] and an ion at m/z 214 has been observed as a contaminant in water [29].…”

Detailed studies have been made using different source gases and solvents in a Micromass Quattro mass spectrometer under positive ion atmospheric pressure chemical ionization conditions. The major background ions from nitrogen, air, or carbon dioxide were investigated by tandem mass spectrometry, followed by similar studies on solvents commonly employed in normal- and reversed-phase high-performance liquid chromatography, namely, water-acetonitrile, acetonitrile, and dichloromethane, with nitrogen, air, or carbon dioxide; hydrocarbon solvents were studied using nitrogen. Spectra were interpreted in terms of the gases, solvents, and their impurities. The acetonitrile spectra provided clear evidence for both charge exchange and proton transfer, the former being facilitated by the introduction of some air into a flow of nitrogen. Radical cations of acetonitrile dimers, trimers, and tetramers were observed, as were protonated dimer and trimer species. Examination of the analytical response of four polycyclic aromatic hydrocarbons in various hydrocarbon solvents, with nitrogen gas, showed that the sensitivity of detection for an analyte and its ionization mechanism are dependent on both the analyte structure and the solvent, with pyrene showing the highest sensitivity, phenanthrene and fluorene being intermediate, and naphthalene having the lowest sensitivity. The degree of protonation followed the same trend. Signal intensity and degree of protonation were dependent on the alkane solvent used, with isooctane providing the best overall sensitivity for the sum of protonated molecules and molecular ions. The ions observed in these studies appeared to be the most stable ions formed under equilibrium conditions in the source.

“…However, during the past few years, the atmospheric pressure ionization (API) techniques, electrospray (ESI), and atmospheric pressure chemical ionization (APCI) are of choice because they are ca. two orders of magnitude more sensitive than any others interfaces to determine organic contaminants [13,[110][111][112]. The high sensitivity of the API interfaces is illustrated in (Fig.…”

Recent experiences with liquid chromatography-quadrupole ion trap-mass spectrometry (LC-QIT-MS), as an analytical tool for determining trace amounts of organic contaminants in food and environmental samples, are addressed in this review. A brief introduction to the fundamental theory for quadrupole ion trap devices illustrates possibilities and limitations of this technique. Special attention is paid to the impact of sample preparation and chromatography on the ionization efficiency of analytes isolated from complex food and environmental matrices. The capacity to provide useful data for quantifying organic contaminants, and the possibility of obtaining structural information for identifying target and non-target compounds, are discussed. The flexibility, high sensitivity and multi-stage tandem mass spectrometric capability of the QIT are all illustrated. Contemporary applications of this technique to study organic contaminants in food and environment are presented.
