Application of Microflame Atomizer to Gas Chromatography-Atomic Absorption Spectrometry

One of the successful methods for the determination of organometallic compounds is the combination of Gas Chromatography-Atomic Absorption Spectrometry (GC-AAS). The atomizer of AAS was connected with the column of GC by a transfer tube. Three types of the atomizer were reported as flame burner,electrothermal quartz tube and graphite furnace. A large amount of gas or electric energy was required to produce a high temperature for the atomization of analytes, A microflame atomizer of GC-AAS was developed in this paper to circumvent above problems. The volume of the atomizer is one-fifth of the normal flame burner, and a hydrogen gas was used as the carrier gas (35ml/min) and the fuel gas for the atomization of analytes.
