Examination of Iodine Species in the Complex Salt Environment of Marine Aerosols

摘要

This technique provides a robust method for quantifying iodine species in a complex, high salt matrix without sample pretreatment. The advantage of an ion chromatography system equipped with an ion-exchange column allows for complete separation of iodate and iodine from the matrix of sea water aerosols. Quantitation curves generated on the MSQ Plus and TSQ Quantum Access mass spectrometers show excellent linearity. The use of a triple stage quadrupole instrument provides detection of low level iodate and iodide without any interference from the highly complex matrix. If quantification of further analytes in sea water, such as bromate, is desired, these analytes may be detected in the mass spectrometer without any modification to this LC separation method.
