Analysis of the petroleum products by chromatographic methods The development of oil and gas industry - one of the priorities of the Russian economy. Oil and gas are among the most competitive Russian goods, and enjoy a high and steady demand from the world’s consumers. Therefore, special attention is paid to the quality of products. One of the methods for quality control of oil - gas chromatography. Today - it is widespread physical and chemical methods. The article is devoted to the definition of the component composition of petroleum products, including liquefied petroleum gas by gas chromatography according to the regulations.

iFunnel Technology for Enhanced Sensitivity in Tandem LC/MS systems from Agilent Electrospray ionization (ESI) has proven to be robust and widely applicable for the analysis of many types of chemical compounds. Agilent’s new iFunnel Technology combines the high ESI ion generation and focusing of Agilent Jet Stream technology with a hexabore capillary sampling array, which enables a much larger fraction of the ESI spray plume to enter the mass spectrometer ion optics. A unique dual-stage ion funnel allows increased ion transmission, while evacuating a much higher gas load. This innovative design reduces contamination and neutrals to greatly improve overall system signal and reduce system noise. This technical overview demonstrates the iFunnel Technology on the new 6490 Triple Quadrupole LC/MS System enabling zeptomole sensitivity for the first time in a quadrupole based tandem mass spectrometer at conventional flow rates.

Factors affecting electrical comminution performance Factors affecting electrical comminution performance were investigated through experimental work and numerical simulations. The effects of feed size, under-sieve classification, incremental breakage and energy input level on particle pre-weakening and mineral liberation were tested with six ore samples. These results were used to interpret the differences in breakage and liberation for various ores. The results showed that the induced electrical field is strongly dependent on the electrical properties of minerals, the grain size, the location of the conductive minerals in rocks, and the particle shape/orientation. Understanding how the machine-related factors and ore-related factors affect the electrical comminution performance will assist in the machine scale up development.

Non-destructive molecular profiling of the skin using Confocal Raman microscopy Confocal Raman spectroscopy has been employed as non-destructive and label free tool for molecular profiling of the skin. Molecular profiling of the skin is important for cosmetic dermatological, skin cancer, defense and security research. Renishaw’s inVia Raman microscope was applied to excised porcine skin to spatially resolve the chemical composition in the skin at different depths. Both intrinsic biomolecules of the skin and intrinsic topically applied chemicals were profiled. This work demonstrates the potential for Renishaw’s inVia Raman microscope to be applied to skin research in vivo and ex vivo.

Analytics of biodiesel fuels A number of new GOST methods have appeared recently in Russian Federation identical to those of EN methods. These methods have benchmarked the forthcoming of biodiesel fuel to our reality. This forthcoming is so far virtual since biodiesel fuels are not produced in our country, but still real: the control of biodiesel additives in diesel fuel “Euro” is obligatory even in their absence. This article describes briefly the method of manufacturing of biodiesel fuel and analytical methods for its quality control.

Optimization of liquid chromatography with mass spectrometric detection method for the qualitative and semi-quantitative proteomic analysis The proteome is the entire complement of proteins including the modifications made to a particular set of proteins, produced by an organism or system. This will vary with time and distinct requirements, or stresses, that a cell or organism undergoes. In contrast, the genome is very dynamic proteome: the expression pattern of proteins in the body cells varies depending on the physiological functions of cell differentiation and raising environmental factors. In the last decade, the proteomic analysis involve widely using of high-tech, highly effective, informative and sensitive methods such as high performance liquid chromatography, mass spectrometry and the use of protein chips with different types of detection. For quantitative proteomics of induced differentiation cancer cell line HL-60 was used methods LC / MS / MS.
