Abstract.
Multicapillary gas chromatography has been applied to the speciation of organomercury compounds. Basic investigation of the fundamental properties of multicapillary columns, to evaluate their potential and limitations as a rapid separation unit, are presented. For analysis of methylated and ethylated mercury compounds a complete separation can be performed within 45 s under isothermal conditions. The adaptation of the technique for use with a purge and trap system and with an element-selective plasma-emission detector results in a compact and effective system for mercury speciation. Results from analysis of certified reference materials were in good agreement with certified values within the significance levels.
