APPLICABILITY: This method is a simultaneous elemental analysis, not compound specific. Verify that the types of compounds in the samples are soluble with the ashing procedure selected. Because this method deals with wipes samples it is important to keep in mind that the values obtained are qualitative. INTERFERENCES: Spectral interferences are the primary interferences encountered in ICP-AES analysis. These are minimized by judicious wavelength selection, interelement correction factors and background correction. OTHER METHODS: This method supplements NMAM Method 7300 [1]. Additional element methods, whether single element or multi-element, may be found in NMAM. Alternate instrumentation includes flame atomic absorption spectroscopy for certain elements and graphite furnace AAS for increased sensitivity.
