Summary

Molecular Ions in Spark Source Mass Spectra of Sulphide-Graphite Mixtures

Investigations of the intensities of CS2 n+ ions (n=1,2,3) as a function of sparking voltage, electrode gap, accelerating voltage and electrode composition were carried out using two different mass spectrometers and various sulphide-graphite mixtures.

The molecular ion intensity was found to increase with increasing electrode gap and sparking voltage. In these experiments, no CS2 3+ ions were observed. The intensity of CS2 3+ ions relative to S+ ions was less than 9·10−9.
