Measurement and Results - Interferences between bismuth (Bi) and HF

 
Is there a known interference between Bismuth and HF? Meaning, if I run an internal standard with Bismuth and a sample matrix or standard with trace HF (2% which is then serially diluted in the standard or sample) and I see an effect on my Bi in the internal standard, why might this be happening? The element of interest is Tantalum.

We’re not aware of any interferences between Bi and HF, and would not expect trace HF to significantly diminish or enhance Bi signal intensities in ICP applications. The presence of Bi in solution, however, will reduce the effectiveness of fluoride as a complexing ligand for stabilizing other metals. In other words, if HF is used to stabilize Ta in solution, then increasing amounts of Bi will tend to pull fluoride (F) away from Ta, to the extent that high Bi/Ta ratios could compromise Ta stability. It is not expected that this effect could explain your results, but a carefully designed study could eliminate or confirm it as a possibility.
