Method 1640: Determination of Trace Elements in Ambient Waters by On-LineChelation Preconcentration and Inductively Coupled Plasma-Mass Spectrometry. Draft, January 1996

摘要

The method is for the determination of dissolved elements in ambient waters atEPA water quality criteria (WQC) levels using on-line chelation preconcentration and inductively coupled plasma-mass spectrometry (ICP-MS). It may also be used for determination of total recoverable element concentrations in these waters. The method contains QC procedures that will assure that contamination will be detected when blanks accompanying samples are analyzed.
