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 | Nu Plasma 1700 is a large-geometry, double-focusing HR-MC-ICP-MS with ~1,700 mm mass dispersion. The large geometry raises the base resolving power to >800 (10% valley definition) at full sensitivity, and edge resolving power reaches >30,000 (5–95% edge definition) by narrowing the continuously Nu Plasma 1700 is a large-geometry, double-focusing HR-MC-ICP-MS with ~1,700 mm mass dispersion. The large geometry raises the base resolving power to >800 (10% valley definition) at full sensitivity, and edge resolving power reaches >30,000 (5–95% edge definition) by narrowing the continuously adjustable source entrance slit. Each of the 16 Faraday detectors and up to 5 ion-counting detectors carries an independently adjustable high-resolution collector slit, enabling simultaneous true high-resolution operation across the entire array....
