Method 200.8

Elements by Ion Coupled Plasma / Mass Spectrometry (ICP/MS) 

Scope:

This method provides procedures for determination of dissolved elements in ground waters, surface waters and drinking water. It may also be used for determination of total recoverable element concentrations in these waters as well as wastewaters, sludges and soils samples.

For total recoverable analysis of a solid or an aqueous sample containing undissolved material, analytes are first solubilized by gentle refluxing with nitric and hydrochloric acids.  For the determination of dissolved analytes, the sample must be filtered through a 0.45 µm filter immediately after collection.  An aliquot of the filtered aqueous sample or for the “direct analysis” total recoverable determination of analytes in drinking water where sample turbidity is <1 NTU, the sample is acidified with nitric acid, and then diluted to a predetermined volume and mixed before analysis.  Analyses for both preparations are performed by ICP/MS (inductively coupled plasma mass spectrometry).

Aqueous samples containing suspended or particulate material ≥ 1% (w/v) should be extracted as a solid type sample.
