Given that arsenic is a toxin and selenium is an essential nutrient, their precise quantification is crucial for understanding their geochemical cycles and environmental impacts.

However, ICP-MS analysis of arsenic and selenium is complicated by spectral interferences, especially from rare earth elements (REEs) like dysprosium or gadolinium, which can lead to false positives.


This application note explores the use of triple quadrupole (TQ) ICP-MS to mitigate these interferences and improve the monitoring of trace levels of arsenic and selenium in complex samples.
