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.
How to Meet the Challenges of Soil Analysis

Soil contains an array of micronutrients and these form the building blocks for crops destined to be eaten, processed, or fed to livestock. It is vital for both consumers and industry that micronutrients in soil be measured in order to track or prevent soil depletion while ensuring effective crop rotation and fertilizing.
Accurately analyzing soil for elemental content poses a number of challenges during sample preparation.
Conventional sample preparation involves an open vessel technique with an acidified sample being heated to near boiling before elements are extracted for analysis. This extraction method is slow, generally taking over 4 hours to complete. It is also prone to the loss of volatile analytes and contamination from environmental sources.
