Rapid Analysis of High-Matrix Environmental Samples Using the Agilent 7500cx ICP-MS Application
The document describes how the Agilent 7500cx ICP-MS, equipped with the Octopole Reaction System (ORS), can analyze typical environmental samples in less than 2.5 minutes per sample. By operating the ORS in helium mode, the instrument removes or reduces practically all matrix-based interferences without the need for time-consuming, matrix-specific method development or mode switching. This allows for the analysis of an entire environmental suite of elements, including mercury and major elements like sodium, potassium, calcium, magnesium, aluminum, and iron, under identical generic conditions.

It is possible to analyze an entire environmental suite of elements in less than 2.5 minutes per sample.
No, all elements are measured under identical helium mode collision conditions and no mode switching is necessary.
The suite includes Hg and major elements such as Na, K, Ca, Mg, Al, and Fe.
