Resolving Difficult Interferences in Metallurgical Samples
Sponsored by PerkinElmerFeb 18 2021
ICP-OES is frequently employed in the determination of trace elements in metallurgical matrices due to its ability to accommodate high levels of dissolved solids with no need to utilize matrix separation schemes or special sample introduction components.
Because sample preparation does not require large dilution factors, analyte levels introduced to the instrument will not be significantly impacted by dilutions.
Despite these notable benefits, spectral interferences may pose a particular challenge when using ICP-OES for the analysis of trace metals in metallurgical matrices. A large number of elements display many emission lines; for example, iron has approximately 20,000.
