摘要：

A hydrogen atmosphere flame ionization detector (HAFID), modified from a commercial FID, is demonstrated as a selective gas chromatographic detector for the determination of antiknock agents in gasoline. By a simple one to ten dilution of a leaded gasoline, alkyllead compounds were detected with no interference from overlapping chromatographic peaks of hydrocarbons. The two samples analyzed in this study contained 1.22 and 0.38 g/gal Pb as tetraethyllead (TEL). Similarly, methylcyclopentadienylmanganese tricarbonyl (MMT), corresponding to 6 mg/gal of Mn, could be easily detected in an unleaded gasoline sample. Detection limits were calculated to be 7.2X10-12 g/s of Pb and 1.7X10-14 g/s of Mn. Optimal operating conditions are discussed. © 1979, American Chemical Society. All rights reserved.
