| Abstract: | Abstract A specific method to determine two anti-icing additives (ethylene glycol monomethylether, EGME and diethylene glycol monomethylether, DEGME) in jetfuel is described. This method is based on a gas-chromatographic technique using a mass spectrometer detector and the monitoring of selected ions (GC-MS-SIM). This specific technique has shown to be an accurate and rapid tool to carry-out these measurements in such a complex hydrocarbon matrix. The GC-MS-SIM technique, because of its specificity, does not require sample pre-treatments other than trichloroethylene (TCE) which has been selected as an internal standard. The analysis of both EGME and DEGME can be performed in less than 10 minutes in a sample of 1–5 mL. Several fuel samples were analyzed and the results compared with two standard methods. |
