Inductively coupled plasma mass spectrometers (ICP-MS) utilize inductively coupled plasma for sample ionization and an MS for ion separation and quantification. The low detection limits and high productivity possible with ICP-MS are particularly useful for trace metal analysis and environmental testing. Common components of an ICP-MS system include a sample introduction system, an ion source, a vacuum system, a collision reaction cell, ion optics, a mass spectrometer (often a quadrupole), and a detector. An analytical working range of nine orders of magnitude, detection limits below the ppt range, and aptitude for isotopic analysis are hallmarks of ICP-MS. ICP-MS instruments are commonly configured for routine analyses, high-matrix interference samples, or specific applications, such as work in the semiconductor industry or medical and forensic toxicology fields. Also, be sure to consider any desired customization options, such as chromatographic coupling or use with organic solvents.

| Description | The Attom ES is a double-focusing, single-collector HR-ICP-MS with the analyser and sample introduction system at ground potential. It uses a laminated magnet with FastScan electrostatic deflector optics to cover up to 40% of a given mass range without changing the magnetic field. A unique patented The Attom ES is a double-focusing, single-collector HR-ICP-MS with the analyser and sample introduction system at ground potential. It uses a laminated magnet with FastScan electrostatic deflector optics to cover up to 40% of a given mass range without changing the magnetic field. A unique patented detector attenuation system extends the pulse-counting multiplier to 9 orders of magnitude dynamic range; an optional Faraday detector extends this to 12 orders....
