ICP-MS swiftly analyzes multiple elements with low detection limits (down to ng/L) and a ± 2% relative standard deviation. Liquid samples enter in plasma as aerosol and at 7000 K vaporized, atomized and ionized. Ions enter the mass spectrometer via a conical lens system, separating from the argon stream maintaining the plasma. Electrostatic lenses direct ions to remove non-ionized species and navigate through a system removing spectral interferences. Utilizing an octapol collision cell with He kinetic energy discrimination and a reaction cell with NH
3, H
2, Xe, ions are sorted based on m/z by a quadrupole mass analyzer, combining direct and alternating currents.
