Laser ionization gas chromatography/mass spectrometry of tetraethyltin

A new method for detecting tetraethyltin that combines the high efficiency of laser ionization, the selectivity of capillary column gas chromatography, and the large throughput of a time-of-flight mass spectrometer is demonstrated. Detection limits of 2.5 pg of tetraethyltin/mL or 1.5 fg of tetraeth...

Zusammenfassung:A new method for detecting tetraethyltin that combines the high efficiency of laser ionization, the selectivity of capillary column gas chromatography, and the large throughput of a time-of-flight mass spectrometer is demonstrated. Detection limits of 2.5 pg of tetraethyltin/mL or 1.5 fg of tetraethyltin absolute have been obtained. These values correspond to 1.3 pg of tin/mL or 750 ag of tin absolute. This method should be generalizable to other elements.
