| Abstract |
This article describes the development of a method for determining the presence of methyl tert-butyl ether (MBTE), in a matrix of gasoline vapours and in liquid gasoline samples, with the simultaneous analysis of benzene, toluene, xylenes and total hydrocarbons. An assessment of the method's performance based on field tests at different service stations is also included. The method recommends collection of air samples on 400- and 200-mg coconut-shell charcoal tubes in series, desorption in carbon disulfide, split-vent injection, gas chromatography (GC) analysis using a capillary column and detection by flame ionization detector. The analysis of liquid gasoline samples is accomplished by direct GC injection. The method worked well for all these samples. The majority of personal exposures to MBTE were near the detection limit. MBTE concentrations in gasoline bulk samples varied from non-detectable to 12.4 percent. |
