“…Other detectors that can be used include both the nitrogen and sulphur chemiluminescence detectors (NCD and SCD), as well as the nitrogen-phosphorous detector. [83] For sulphur-and phosphorus-containing compounds, flame photometric detection can be successfully used [109] . Newer high-speed quadrupole mass spectrometers (qMS) can also be used in a limited fashion.…”

Comprehensive two-dimensional gas chromatography (GC × GC) and its direct applications to measurement of volatile and semivolatile organic compounds in air are reviewed and discussed. The paper includes a brief discussion of the instrumental set-up and theory for the comprehensive GC × GC hyphenated with different detection techniques. Several reviewed types of modulators demonstrate that the applications of comprehensive GC × GC are still under development, underlying the flexibility of the system as well. The fundamental differences between one-dimensional and twodimensional gas chromatography, regarding their potential to provide both qualitative and quantitative information, are also presented. The present article focuses on reported applications dealing with the analysis of volatile and semivolatile organic compounds from air (gas and particles related), but some data related to other sample types analyzed with comprehensive GC × GC are also briefly presented. The paper supports the idea that there is a good reason for interest in comprehensive GC × GC, which seems to be a suitable technique for applications in the separation of complex mixtures of volatile and semivolatile compounds.

“…For example, gas chromatography (GC) and, particularly, comprehensive two-dimensional GC are very efficient in the separation of volatile and semi-volatile compounds of petroleum [ 5 ]. Their combinations with selective detectors, such as, for example, sulfur chemiluminescence detector [ 6 ] and flame photometric detector [ 7 ], or with a more universal mass selective detector [ 8 ], allow the identification of a wide range of sulfur compounds. Unfortunately, GC techniques are limited by the volatility of analytes and are not suitable for high molecular weight and polar components of crude oil.…”

The Use of Polydialkylsiloxanes/Triflic Acid as Derivatization Agents in the Analysis of Sulfur-Containing Aromatics by “Soft”-Ionization Mass Spectrometry

et al. 2022

Polycyclic aromatic sulfur-containing compounds are widely distributed in oil, especially in its low-volatile and heavy fractions (resins, asphaltenes), and this dictates the need for their determination when reliable methods for sulfur removing, cleaning and processing oil are developed. In these cases, “soft” ionization mass spectrometry methods, based on electrospray ionization (ESI) and matrix-assisted laser desorption/ionization (MALDI), are particularly effective. However, aromatic sulfur-containing compounds have low polarity and cannot be readily ionized by these methods. To overcome the problem, their preliminary conversion into sulfonium salts by the action of alkyl iodides and a silver-containing agent is widely used. In the process of developing more economical derivatization methods, we found a rather unexpected possibility of implementing S-alkylation of organic sulfides with commercial polydialkylsiloxanes (alkyl = CH3 or C2H5) in the presence of triflic acid (CF3SO3H) as a superacid co-alkylating agent. For homologous dibenzothiophenes as a typical model representative of petroleum sulfur-containing aromatic compounds, ESI and MALDI mass spectra exhibited the signals of corresponding S-alkylsulfonium salts with a high signal-to-noise ratio. A rational mechanism for the described chemical transformation is proposed, including the indispensable activation by triflic acid and the cleavage of the Si-C bond. Specific collision-induced dissociation of corresponding S-alkylated sulfonium cations is considered. The applicability of the derivatization approach to the analysis of petroleum products by high-resolution mass spectrometry is demonstrated.

“…[15][16][17] While these devices provide good analytical performance, the relative cost and maintenance associated with them is also often a concern. 18,19 One of the most widely used sensors in this regard is the flame photometric detector (FPD) [20][21][22][23][24][25][26][27][28][29][30] due in part to its high sensitivity and selectivity for sulfur 31,32 along with its rugged design and simple operation. 33 Additionally, the FPD is a relatively inexpensive detector that can also respond selectively to other heteroatoms, such as phosphorus, tin, and several metals.…”
