Analysis of Highly Mineralized Aqueous Solutions by ICP-AES
May 13, 2016
EPA methods 200.7 and 6010 specify ICP; however, analysis of the major components may involve dilution of off-scale peaks, making the analysis more difficult. This work demonstrates a method that uses low-sensitivity analytical lines for the high-concentration major components and high-sensitivity analytical lines for the low-concentration trace components. This eliminates the need for multiple dilutions to get major elements on-scale.
