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 | Sapphire XD is a dual-path MC-ICP-MS/MS that extends the Sapphire platform with a fully retractable Double Wien mass filter (permanent magnets + lens field arrays) and an Xtra Dispersion (XD) fixed collector array. The mass filter can be inserted prior to the hexapole collision/reaction cell for MS/Sapphire XD is a dual-path MC-ICP-MS/MS that extends the Sapphire platform with a fully retractable Double Wien mass filter (permanent magnets + lens field arrays) and an Xtra Dispersion (XD) fixed collector array. The mass filter can be inserted prior to the hexapole collision/reaction cell for MS/MS operation (e.g. Rb-SrF mass shifting) or used alone to suppress space-charge effects. The XD collector provides 25% natural dispersion and accommodates up to 28 Faraday cups and 6 ion-counting detectors....
