摘要
Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) is often applied to determine sulfur in minerals,proteins, fossil fuels and other materials. The study of sensitivity, limit of detection and background noise during determination of sulfur, using both Quadrupole Inductively Coupled Plasma-Mass Spectrometry (Q-ICP-MS) and Sector Field Inductively Coupled Plasma-Mass Spectrometry (SF-ICP-MS), are presented in this paper. The results indicate that the matrix of 2% HNO3 is more suitable for sulfur determination by ICP-MS. In addition, the reason for higher sulfur sensitivities for both S2- and SO32- is that the formation of aerosols (H2S and SO2) in 2% HNO3 improves atomization efficiency.
