Download or read book Analysis of Middle Distillate Fuels by High Resolution Field Ionization Mass Spectrometry written by Ripudaman Malhotra and published by . This book was released on 1987 with total page 85 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have developed an analytical method for the rapid and detailed chemical characterization of distillate fuels using high-resolution field ionization mass spectrometry (HR-FIMS). Field ionization produces only the molecular ions for most compounds and is therefore particularly useful for the analysis. A vintage AEI MS-9 mass spectrometer was refurbished and modified to house an SRI volcano-style field ionizer. By operating the mass spectrometer at a resolving power of 3000, all the hydrocarbon z-series present in the fuel can be resolved. Software was written for sorting the peaks according to their z-series, applying the appropriate response factors, printing and plotting the reports, and averaging replicate analyses. Keywords: Distillate, Fuel, Analysis, Jet fuel, Diesel fuel, Mass spectrometry, Field ionization, High resolution series.

This book was released on 1980 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interim technical report describes work completed during the first twelve months of a research program to develop field ionization mass spectrometry for quantitative analyses of middle distillate fuels. The relative field ionization sensitivities were measured for 90 compounds from petroleum, shale, or coal. The FIMS sensitivities for naphthalenes are from 2 to 3 times greater than for saturates, an advantage for detecting these minor components. Sensitivity was also high for nitrogen and sulfur containing compounds which will increase the level at which these materials may be detected in fuels. Distillation of the fuel sample from a solids probe into the FIMS source was found to not provide sufficient separation of compounds such as naphthalenes and saturates. These compounds will be separated using high resolution FIMS. The precision of the proposed analysis method was evaluated with an authentic jet fuel sample, and it was found that the coefficient of variation of minor components averaged 6 percent while that of larger components was 2 or 3 percent. The use of high resolution FIMS together with a batch inlet system and computerized data collection and analysis system appears to be a highly promising technique for providing detailed quantitative data on the chemical composition of middle distillate fuels.

This book was released on 2000 with total page 77 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent military operations have identified an immediate need for a rapid means of identifying and analyzing fuels in the field. Fuel types requiring analysis are primarily those for ground vehicles and support equipment including diesel gasoline and kerosene. The use of improper or contaminated fuels can be detrimental to equipment resulting in more frequent maintenance problems shortened lifetimes of fuel-related components (e.g. fuel filter) and in some cases complete failure. As a result an increase in combat service support on or near the battlefield is required as maintenance personnel and spare parts must be readily available. Common contaminants in fuels include water biological growth and by-products of normal fuel degradation. In addition the quality of host nation fuel resources and captured fuels may be inferior Other than visual inspection the only means available for analyzing fuels of questionable quality in the field requires transportation to a non-combat site mobile laboratory or other facility with analytical equipment. Therefore the military is interested in acquiring simple rugged instrumentation appropriate for field use and capable of rapidly determining fuel type and quality. Although a number of analytical techniques are available for fuel analysis only a handful are useful in determining a fuel's suitability for consumption. Some of these include density viscosity aromatic content net heat of combustion cetane number boiling point and the cold temperature properties (e.g. cloud point pour point freeze point). Furthermore some of these properties (e.g. density and net heat of combustion) may be used to discriminate fuel type. Chemometrics is a branch of chemistry that uses mathematical and statistical routines to model a variety of chemical and physical properties.

Book excerpt: Field Ionization Mass Spectrometry focuses on developments in field ionization (FI) mass spectrometry and describes its applications in physical chemistry, with emphasis on mass spectrometric problems. Physico-chemical problems as well as problems of chemical analysis are considered based on issues such as the probability of field ionization; field dissociation and charge distribution; kinetics of ion decomposition in high fields; negative ions; surface diffusion; activation of FI emitters; and elucidation of the structures of organic compounds. This book is comprised of four chapters and beg.
