ICP-MS is an analytical technique used to measure the concentration of metals and other elements. Samples are usually introduced as liquids, but ICP-MS can also be used to measure elements in solid materials and gases. ICP-MS consists of a high temperature ion source (the plasma), a mass spectrometer (usually a quadrupole mass filter), and a detector. The plasma is at atmospheric pressure and the spectrometer and detector are in a vacuum chamber, so an ICP-MS instrument also needs an interface and ion lens to transfer the ions through the system.
A liquid sample is pumped through a nebulizer to form an aerosol that is carried in a gas stream to the plasma. The plasma is a high temperature electrical discharge which vaporizes the sample material and then atomizes and ionizes the elements. The ions pass through an interface into a vacuum chamber, where they are separated from photons, neutral particles, and interfering ions using an ion lens and a collision/reaction cell (CRC). The analyte ions are then sorted by the quadrupole mass filter and each mass is passed to the detector to be counted.
ICP-MS is used for multielement analysis in practically all industries from food safety, environmental monitoring, and pharmaceutical testing, to semiconductor manufacturing, geochemical analysis, and life science research. ICP-MS measures each sample in around 3 minutes, so it is particularly beneficial in high-throughput laboratories. ICP-MS can quantify nearly every element (and measure isotopic composition) at concentrations from parts per trillion to percent and it can also be connected to a chromatographic system for speciation analysis.
