When we determine the composition of metal alloys using ICP-OES that require HF to digest, is it necessary to use the HF-Resistant sample introduction if we are not testing for Si, B or Na?
Would this cause any damage to the quartz Spray Chamber or torch?
On a related note, for the compositional analysis of AuSn alloys, would a digestion by the use of HBF4 by preferred to an Aqua Regia digestion, due to concerns of Sn stability in Nitric Acid?
Thirdly, would the use of HBF4 also require the use of the HF-Resistant Sample Introduction if we are not testing for Si, B, or Na?
Any thoughts on the use of HBF4 instead of HF when digesting elements that normally require HF?
