Attenuation mode on the Avio 220 Max ICP-OES for simplified analysis of high concentration elements

In ICP-OES analyses, it is common to measure elements present at high concentrations, such as minerals, matrix elements in alloys, and plating bath solutions, to name just a few examples. In this application note, PerkinElmer shows that the Avio 220 Max hybrid simultaneous ICP-OES incorporates Attenuation mode, a unique mode to selectively reduce analyte signal, allowing higher concentrations to be measured, thereby extending the dynamic range of ICP-OES without affecting the ability to measure analytes present at lower concentrations. The benefits of Attenuation mode to the user include simplified methodology, minimal sample dilution, and the ability to measure higher concentrations without having to use and characterize alternate wavelengths.
