7900 ICP MS-uses a high- temperature argon plasma torch to ionize atoms in samples.
Once ionized, sample atoms are routed through a mass spectrometer, which separates and detects
sample constituents according to their mass and charge. The Agilent 7900 has a dynamic solution
concentration range due to argon dilution capabilities, making it possible to run samples in the ppm
range as well as very low (below ppt) for trace elements.

The Agilent 7900 ICP-MS can be used to analyze a diverse array of solution sample types with widely
varying solute concentrations, for example from freshwater, seawater, soil extracts, dissolved minerals,
and digested plant and animal tissue.

ICP-MS, where ppt is parts per trillion and ppb is parts per billion (courtesy of PerkinElmer, Inc.).
Elements detected by an IC are also included and indicated with orange crosses.
