摘要
The suitability of various atomic absorption and atomic fluorescence atomizing systems connected to a gas chromatograph is compared for the determination of alkyl lead compounds. An electrothermally heated graphite tube gives the highest sensitivity but quartz tubes heated either in an air-acetylene flame or by electrical resistance wire provide adequate sensitivity for most applications. A solvent peak" absorption thought earlier to be due to organic molecular absorption of radiation at the lead wavelength was shown to be due to deposition and remobilization of lead. © 1979."
