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