This document introduces the advantages of Agilent 7700x ICP-MS technology in drinking water analysis. This technology uses the 3rd generation Octopole Reaction System (ORS3) technology to effectively remove polyatomic interferences. He mode is simple and easy to use, and the 7700x ICP-MS can remove all polyatomic interferences in a single set of conditions without requiring any prior knowledge about the sample, and without the need for complex mathematical corrections. This makes setup easier, detection limits are lower, analysis is faster, and interference removal is improved, especially for the difficult plasma-based interferences affecting iron and selenium. Currently, Se detection limits of less than 20ppt are routinely achievable in He mode.
