Navy Fuels Analytical Chemistry.
Abstract
TRW developed new and unique analytical methods in support of the Navy's program in mobility fuels analysis. These methods include 1) the separation and isolation of different classes of organosulfur compounds in JP-5 by high performance liquid chromatography with silver nitrate impregnated silica gel columns, 2) the separation and identification of individual sulfur compounds in the HPLC fractions by capillary gas chromatography with detection by a) simultaneous flame ionization and Hall electrolytic conductivity, and b) mass spectrometry, and 3) the quantitation of nanogram amounts of sulfur compounds in as-received fuel and the HPLC fractions using a TRW-developed 'integrating sulfur detector' based on a modification of the Hall detector. This analytical scheme can be used to characterize the changes in sulfur compound distribution in JP-5 fuels arising from different crudes, refining conditions, aging, and thermal and oxidative stressing.
