“…Efim Brodskii et al have extensively used GC/MS for the detection of oil spill residue in stream sediments in the area of emergency mazut overflow from industrial enterprise. 230,231 The employed complex method adopted the peaks of n-alkanes, the ratio between n-alkanes with even and odd numbers of carbon atoms, the peaks of biomarkers (isoprenanes, steranes, triterpanes etc. ), the predominance of methyl-and alkyl-substituted mono-, biand polynuclear aromatic hydrocarbons over unsubstituted aromatic hydrocarbons and other features.…”

The present review covers the main research in the area of mass spectrometry from the 1990s which was about the same time as the Russian Federation emerged from the collapse of the Soviet Union (USSR). It consists of two main parts-application of mass spectrometry to chemistry and related fields and creation and development of mass spectrometric technique. Both traditional and comparatively new mass spectrometric methods were used to solve various problems in organic chemistry (reactivity of gas-phase ions, structure elucidation and problems of identification, quantitative and trace analysis, differentiation of stereoisomers, derivatization approaches etc.), biochemistry (proteomics and peptidomics, lipidomics), medical chemistry (mainly the search of biomarkers, pharmacology, doping control), environmental, petrochemistry, polymer chemistry, inorganic and physical chemistry, determination of natural isotope ratio etc. Although a lot of talented mass spectrometrists left Russia and moved abroad after the collapse of the Soviet Union, the vitality of the mass spectral community proved to be rather high, which allowed the continuation of new developments in the field of mass spectrometric instrumentation. They are devoted to improvements in traditional magnetic sector mass spectrometers and the development of new ion source types, to analysis and modification of quadrupole, time-of-flight (ToF) and ion cyclotron resonance (ICR) analyzers. The most important achievements are due to the creation of multi-reflecting ToF mass analyzers. Special attention was paid to the construction of compact mass spectrometers, particularly for space exploration, of combined instruments, such as ion mobility spectrometer/mass spectrometer and accelerating mass spectrometers. The comparatively young Russian Mass Spectrometry Society is working hard to consolidate the mass spectrometrists from Russia and foreign countries, to train young professionals on new appliances and regularly holds conferences on mass spectrometry. For ten years, a special journal Mass-spektrometria has published papers on all disciplines of mass spectrometry.

“…3 To monitor groundwater contamination by fuel, several chemical contaminants must be quantitated at trace level concentrations in complex water matrices with considerable potential for interference from other trace impurities. 5 Membrane introduction mass spectrometry (MIMS) 6 is a powerful technique for selective and real-time monitoring of volatile organic compounds (VOCs) 7 or semi-volatile organic compounds (SVOCs) 8 directly from aqueous solutions. In MIMS, the introduction of an analyte into the mass spectrometer occurs via selective transport through a silicone membrane.…”

The solubilization of ethanol and the aromatic hydrocarbons benzene, toluene and the isomeric ethylbenzene and xylenes (BTEX) in water in contact with commercial samples of ethanol-containing Brazilian gasoline was monitored on-line by membrane introduction mass spectrometry (MIMS) and BTEX and ethanol concentrations in water after prolonged contact were measured by flow injection analysis (FIA) coupled with MIMS (FIA-MIMS). The cosolvent effect of ethanol, which is known to increase BTEX solubility in water, was also found to speed up BTEX solubilization as compared with ethanol-free gasoline. The ethanol cosolvent effect was also compared with that of methyl tert-butyl ether (MTBE). Chemometric multivariate analysis applied to FIA-MIMS mass spectra of the ethanol-BTEX aqueous solutions formed after prolonged contact with gasoline samples showed that identical samples cluster closely whereas small variances in BTEX composition occurring among and within the three different types of ethanol-containing Brazilian gasoline are easily detected as they cause great dispersion in the chemometric plots.

Since there is not any report about simultaneous microextraction of 42 petroleum pollutants (n‐alkanes and polycyclic aromatic hydrocarbons) in water, in the present study dispersive liquid–liquid microextraction (DLLME) using organic solvents lighter than water was applied for simultaneous determination of these compounds in water samples by GC‐flame ionization detection (GC‐FID). In order to achieve the best extraction efficiency, optimization of variables affecting DLLME method was carried out. In this method, an appropriate mixture of extraction and disperser solvents is injected into an aqueous sample, which led to formation of a cloudy solution. The analytes become enriched in the extraction solvent, which is dispersed throughout the bulk aqueous sample. After centrifugation, quantification of the analytes in the organic phase can be performed by GC‐FID. The main advantage of this technique is its quite large surface area between the fine droplets of the extraction solvent and water sample, and the accordingly fast extraction kinetics that results in the rapid achieving of a state of equilibrium and the high enrichment factors (EFs). Under the optimum conditions, EFs in the range of 280–446 were obtained. The proposed method provided low limits of detection (0.1–0.98 µg L−1) and acceptable extraction repeatabilities. It was linear over two orders of magnitude. Finally, petroleum pollutants have been determined in different type of water samples by this method.
