I am a beginner using ICP-MS and having some troubles, there are :
1. I have a trouble to control some of metal contaminants. So, what is the most suitable method for clean up glassware (volumetric flask, pipette, and any glassware) and PE vial?
2. In national standard method, we use 5 mL of Nitric Acid concentrated (typically 65%) and 2% hydrogen peroxide and then diluted to 25 mL final volume (Nitric acid concentration = +/- 13%). Is it possible that we change the volume of Nitric Acid to 1 mL + 2 mL hydrogen peroxide + 4 mL water while digestion? So we have +/- below 3% Nitric acid concentration in final.
3. What is the effect of acid concentration in ICP-MS stability/sensitivity measurement?
Thank you for your kind response.
