Instrument: Inductively Coupled Plasma Mass Spectrometer
An ICP Mass Spec is an instrument that passes nebulized samples into an inductively-coupled gas plasma (8-10000 K) where they are atomized and ionized. Ions of specific mass-to-charge ratios are quantified in a quadrupole mass spectrometer.
Dissolved Pb was measured at the University of Alaska, Fairbanks using an ThermoFinnigan Element 2 Inductively Coupled Plasma Mass Spectrometer coupled (ICP-MS) to an Elemental Scientific SeaFAST S2 (syringe based system).
