Characterization of multicapillary gas chromatography-microwave-induced plasma atomic emission spectrometry for the expeditious analysis for organometallic compounds

Résumé

Multicapillary column gas chromatography (MC-GC)-microwave-induced plasma atomic emission spectrometry (MIP-AES) is evaluated for fast speciation analysis of organometallic compounds. In situ derivatized organomercury, organotin and organolead compounds are separated isothermally within several seconds instead of several minutes required by the conventional procedures. Neither the resolution nor the sample capacity are sacrificed compared with conventional capillary GC with oven temperature gradient programming. Sub-picogram detection limits are obtained. Examples of applications of MC-GC-MIP-AES to speciation of butyltin and organomercury compounds in sediment, and of tetraalkyllead compounds in gasoline are given.
