The Agilent 7700x/7800 ICP-MS Advantage for Drinking Water Analysis

The Agilent 7700x/7800 Series ICP-MS Octopole Reaction System (ORS)
brings collision/reaction cell (CRC) technology to routine environmental
analysis of trace metals in drinking waters. The ORS has been optimised
to significantly improve the performance of helium (He) collision mode for
the removal of polyatomic interferences. He mode is simple and universal,
enabling the 7700x/7800 ICP-MS to remove all polyatomic interferences
under a single set of conditions, withoutrequiring any previous knowledge
about the sample, and without the need for complex mathematical
corrections. The result is easier set-up, lower detection limits, faster
analysis, and improved inter-ference removal, especially for the difficult
plasma based interferences affecting iron and selenium. Selenium detection
limits less than 20 parts per trillion (ppt) are now routinely achievable in He
mode.
