A study of positive ionization electrospray mass spectrometry (ES‐MS) was performed on trimethyllead (TML) and triethyllead (TEL). The system consisted of in‐tube solid phase microextraction (SPME) coupled directly to an electrospray mass spectrometer. Fragmentation patterns of compounds were observed by applying different fragmentation voltages. High voltages produced sufficient fragmentation to elucidate the dissociation of the trialkyllead compounds. Electrospray mass spectrometry has been shown to be a suitable detection system for organolead speciation. Applying fragmentation energy programming, it might be possible to obtain in parallel the molecular and atomic signals of lead compounds. Copyright © 1999 John Wiley & Sons, Ltd.
