摘要：

A new quartz T-tube furnace design based on commercial heater modules was evaluated for the determination of organolead and organotin compounds. Furnace operating conditions for both packed and capillary column operation were optimized by multivariate analysis. Response reproducibility ranged from 1.8 to 3.9% relative standard deviation. Calculated limits of detection were 1.4-2.0 pg for Et(4)Pb (as Pb) and 2.2-5.5 pg for Bu(4)Sn (as Sn). The limits of detection after application of Savitsky-Golay smoothing were 1.1-1.2 pg for Et(4)Pb (as Pb) and 2-3.7 pg for Bu(4)Sn (as Sn).
