Three application notes detail sample analysis in high dissolved solids, line switching to cover large concentration ranges, and improving axial ICP accuracy with easily ionisable elements
Thermo Elemental highlights the range of uses of the Iris Intrepid ICP spectrometer through the publication of three new application notes.
This latest information details sample analysis in the presence of a high percentage of total dissolved solids, the benefits of line switching to cover large concentration ranges within a sample, and how to improve axial ICP accuracy in the presence of easily ionisable elements (EIE). The Iris Intrepid's versatility is demonstrated in three challenging applications, covering radial and axial viewing.
The robust nature of the plasma is shown by the ability to determine sodium levels in fizzy cola in the presence of high concentrations of dissolved solids, in this case, sugar and corn syrup.
The dynamic range of the instrument is well tested by the analysis of trace elements in copper and nickel-plating bath solutions, where the major component can be up to seven orders of magnitude more concentrated than the minor components.
The Iris Intrepid, using the intuitive Teva software, switches wavelength automatically depending on the concentration of the analyte.
The third new application note looks at how improved accuracy can be obtained using axial viewing ICP, which offers improved sensitivity and lower detection limits.
This application note details how to compensate for the interferences from large concentrations of EIE's such as calcium and sodium.
These are the latest additions to the library of application notes available for the Iris Intrepid ICP spectrometer and are available by contacting Thermo Elemental (links above).
