Determination of phenolic antioxidants in JP-5 jet fuels by gas chromatography-mass selective detection

Organic-resistant screen-printed graphitic electrodes: Application to on-site monitoring of liquid fuels

“…The addition of antioxidants in jet fuel is regulated by the standard ASTM-D1655. These compounds have been determined in aviation fuels by gas chromatography with mass spectrometry (GC-MS), [4][5][6][7] high-performance liquid chromatography (HPLC) with electrochemical [3,8] and spectrophotometric detection in the UV region, [9,10] and differential-pulse voltammetry [11]. The determination of antioxidants in biodiesel by electroanalytical techniques is highlighted in a recent review [2] giving emphasis on the pioneering work of Tormin et al [12], in which the amperometric determination of the antioxidant tert-butylhydroquinone in biodiesel was accomplished after large sample dilution in a hydroethanolic electrolyte solution.…”

Synthetic Phenolic Antioxidants in Middle Distillate Fuels Analyzed by Gas Chromatography with Triple Quadrupole and Quadrupole Time-of-Flight Mass Spectrometry

“…Gas chromatography (GC) is a popular analytical method for fuel . In particular, GC/mass spectrometry (GC/MS) with selected ion monitoring (SIM) has been used for SPA by Bartl and Schaff, Pearson, Bernabei et al, and Shin et al, , but these methods were only applied to a small number of analytes. Methods based on GC separation with MS SIM detection generally persist as the most popular analytical methods for determining SPAs in fuels, despite suffering problems such as lack of baseline resolution from the fuel matrix, interferences, incomplete extraction, and poor sensitivity and linearity.…”

Separation & Identification of Organic Compounds in Lubricating Oil Additives Using TLC & GC-MS

“…So, because of these variety and undisclosed chemical composition of additives, analysis of lubricating oil additives is important for quality control of oils and for developing substitute or new products. Various techniques (11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) have been tried in analysis of additives in a variety of matrices, and the majority of these techniques were not applicable to the requirements of our particular project either because of a different matrix or for single known additives (23)(24)(25)(26) . This paper reports a qualitative analysis of the components in an additives blended with base oil (the refining of petroleum crude oil), by using solvent extraction, thin-layer chromatography (TLC), and gas chromatography/mass spectroscopy techniques.…”
