Inductively Coupled Plasma Mass Spectrometer

Inductively Coupled Plasma Mass Spectrometry (ICP-MS) is a highly sensitive elemental analysis technique primarily used for determining the trace elements in samples.trace elements and isotopic compositionICP-MS uses high-temperature plasma to atomize and ionize the sample, and then separates and detects the ions based on their mass-to-charge ratio (m/z) through a mass spectrometer, allowing for the simultaneous analysis of multiple elements with extremely low detection limits.

ICP-MS hasHigh sensitivity, rapid analysis, simultaneous multi-element determination, and wide dynamic range.The advantages include a detection limit that can reachppt (10⁻¹²) levelTherefore, it is particularly suitable for the analysis of trace elements and trace contaminants. During the analysis process, liquid samples are usually converted into aerosol form by the nebulizer and then introduced into the plasma torch, at approximately6000–10000 KIn the high-temperature plasma, it is completely atomized and ionized, forming charged ions that enter the mass analyzer, where they are separated based on their mass-to-charge ratio and the signal intensity is measured by the detector, ultimately obtaining information on the types and concentrations of elements in the sample.
