GCxGC /MS FID) Leco Pegasus two-dimensional gas chromatography-mass spectrometer
The method allows to obtain the group composition of gasoline, kerosene, diesel fuels with high detail. Analysis of group composition of middle distillates is performed in 1 hour, 10 years ago such a detailed analysis would have required a week of work. Availability of GCxGC method allows building models in dependence of fuel characteristics directly on its composition.
Park of gas chromatograph mass spectrometers (Shimadzu GCMS QP2010 Ultra, Trace 1310 GC with single-quadrupole mass spectrometer ISQ 7000, etc.)
The tools allow the identification of components of mixtures of organic compounds by GC/MS in the range of molecular masses from 10 to 1050.
Applications::
- analysis of fuels for the content of specific components, including various impurities;
- qualitative and quantitative analysis of mixtures of various organic compounds;
- determination of geochemical parameters of oils.
Gas chromatographic analysis of gasoline composition (Crystallux-4000M)
The methods of analysis of gasoline fractions with determination of the content of:
- aromatics, including individual compounds (benzene, toluene, ethylbenzene, xylenes);
- olefins;
- n-paraffins;
- isoparaffins+naphthenes.
There is experience in the analysis of both commercial gasoline and components: gasoline cracking, reforming, isomerization, alkylation, straight-run gasoline.
Bruker AVANCE III HD NMR Spectrometer (400 MHz)
Nuclear Magnetic Resonance (NMR) spectroscopy is an informative, non-destructive analytical technique. It provides detailed information on the molecular structure of organic compounds.
NMR spectroscopy of homogeneous solutions: techniques of two-dimensional homo- and heteronuclear correlation experiments on 1H, 13C, 11B, 15N, 31P, 27Al and other magnetic nuclei; spectroscopic techniques based on the nuclear Overhauser effect (NOESY, ROESY); diffusion NMR spectroscopy (DOSY, self-diffusion coefficient).
Applications::
- quantitative and qualitative analysis of mixtures of organic compounds;
- determination of the structure-group composition of fuels, oils, vacuum distillates.
