✦ Synopsis
Quantitation of organosulfur compounds in a hydrocarbon matrix was studied by the precursor scan method of neutralization-reionization mass spectrometry. The CHS' ion was used as a marker selectively to detect and quantify sulfur compounds dissolved in a synthetic hydrocarbon mixture. Precursor ion abundances showed a linear dependence on the organosulfur content in the 1-100% concentration range. Detection limits of 0.5% were achieved, which were limited by the instrument sensitivity. Isobaric interferences of 13C isotopomers from hydrocarbons were negligible. Small interferences from oxygen-and nitrogen-containing additives are discussed. Several neutralization gases were examined to minimize interferences and to maximize the ion abundances.
