摘要:
A gas chromatographic-atomic absorbance (GC-AA) method for the separation and determination of 5 Pb tetraalkyls in air at microgram level is described. It is fast, sensitive and relatively specific. The volatile Pb compounds are collected by a cold trap containing OV-1 at -80.degree. C, swept into the GC, and the effluent is ducted to an AA unit for analysis. At normal AA sensitivity (1X), 0.1 .mu.g of each of the Pb alkyls can be determined with certainty.
