7900 ICP-MS

Description

The Agilent 7900 is an inductively coupled plasma mass spectrometer featuring a quadrupole mass analyzer. It covers a mass range from 2 to 260 u with variable resolution settings. The instrument is designed for high sensitivity, with detection capabilities extending into the parts-per-trillion range, and offers a dynamic range spanning approximately 11 orders of magnitude. A key operational feature is the Ultra High Matrix Introduction (UHMI) technology, which allows the direct analysis of samples containing up to 25% total dissolved solids. Interference reduction is achieved through a helium-mode collision cell. The fast detector and acquisition system support the measurement of rapid transient signals, enabling applications such as single nanoparticle analysis (spICP-MS) and laser ablation studies. This combination of matrix tolerance, sensitivity, and speed makes the system suitable for multielement analysis in various sectors, including food safety, environmental science, geochemistry, and semiconductor manufacturing.
