The Agilent 7800 ICP-MS Advantage for Drinking Water Analysis

July 20, 2015

ICP-MS is widely used for the multielement analysis of trace metals in drinking waters. The newly designed 7800 ICP-MS accurately measured drinking waters for all required elements at regulated levels, without the need for either reactive cell gases or complex interference equations. Using helium collision mode, selenium detection limits less than 20 parts per trillion (ppt) are now routinely achievable.

Simple, Reliable Analysis of High Matrix Samples According to US EPA Method 6020A Using the Agilent 7800 ICP-MS

July 20, 2015

A challenging 15 hour sequence of high matrix soils, waters, seawaters and sediments was analyzed according to US EPA Method 6020A using a new ICP-MS designed for routine applications. With a single collision cell mode for polyatomic interference removal and superior matrix tolerance with an aerosol dilution system, excellent recovery of certified values for six SRMs with no quality control failures throughout the sequence was achieved.
