A simultaneous detection technique of organic sulfur compounds in rainwater by HPLC-ICP-MS
Sulfur containing organic compounds in rainwater were quantified by HPLC-ICP-MS. Several hydrophilic-hydrophobic S species originated from oxidation of dimethyl sulfide were separated by anion exchange chromatography eluted with organic acids, and introduce to inductively coupled plasma (ICP). The S species were ionized as S+ in the high temperature ionization source, and detected as SO+ through an ion-molecular interaction with O2 gas in the collision/reaction cell to avoid the severe background interference of O2+ originated from air and water. The advantages of ICP-MS in matrix robustness and molecular-independent constant sensitivity will enable us to detect unidentified molecules in various environmental samples.
