The Perkin Elmer NexION 200 ICP-MS is an inductively coupled plasma mass spectrometer (ICP-MS), is commonly used to measure the concentration of most elements for rapid, precise and accurate trace (<1000 ppm) determinations in liquid and solid samples (after an appropriate chemical digestion and filtrating). The principle of ICP-MS is to inject a liquid creating an aerosol that is sampled into a plasma created using Argon and an RF field. Thus, the plasma creates a very high effective temperature, which atomizes and ionizes the sample. The ions are detected by a quadrupole mass spectrometer, which analyzes the ions by their m/z ratio.

The NexION 2000 has two features to improve the results, by reducing interference. The first is a quadrupole ion deflector which only allows ions to enter the quadrupole while neutrals and photons are prevented by geometry from entering the quadrupole and impacting the detector.  The second is the Universal Cell Technology™, that can operate in three modes (standard, collision, and reaction), which can either uses collisions of polyatomic interferences to reduce their kinetic energy which are prevented from entering the quadrupole or can use different gases (NH3 or O2) to react with polyatomic interferences to change their mass or neutralize them. An additional feature of the NexION 2000 is a dual detector mode that allows for quantitation over a large dynamic range.

Our ICP systems are equipped with a S23 Autosamplers with three racks (up to 270 samples)

A data treatment computer is available free of charge.
